Seated Towel Stretch	Gastrocnemius + plantar fascia	Seated; leg extended	Loop towel around ball of foot; pull toes toward shin; hold; can bend toes back simultaneously for plantar fascia	3 × 30 sec; 3×/day esp. AM before first steps	Plantar fasciitis morning pain; non-ambulatory patients
Downward Dog (Modified)	Gastrocnemius + hamstring	Yoga downward-facing dog; hands and feet on floor	Alternate heel-to-floor presses; mild dorsiflexion stretch; avoid if insertional Achilles tendinitis	5 × 5-sec alternating heel presses; daily	Active athletes; flexible individuals; avoid for insertional Achilles
Step Calf Stretch (Standard Heel Drop)	Both gastroc and soleus	Standing on edge of step; foot hanging	Lower heel below step level slowly; hold; avoid this for insertional Achilles (increases compression)	3 × 30 sec; 2–3×/day	Mid-portion Achilles tendinitis; calf flexibility; NOT for insertional type
Eccentric Heel Drop (Alfredson)	Gastrocnemius + Achilles tendon	Step edge; bilateral up, single-leg down	Rise on both feet; lower slowly on affected leg over 3 sec; this is TREATMENT not just stretching	3 × 15; 2×/day for 12 weeks	Mid-portion Achilles tendinopathy (gold standard treatment)

Achilles Condition	Best Stretches	Avoid	Additional Treatment
Mid-Portion Achilles Tendinopathy	Gastroc + soleus stretches; eccentric heel drops	Nothing contraindicated for mid-portion	Eccentric loading protocol; heel lift; ESWT if refractory
Insertional Achilles Tendinopathy	Gastroc + soleus stretches on FLAT surface only	Heel drops below step; aggressive dorsiflexion; downward dog	Heel lift orthotic (reduces Achilles angle); ESWT; avoid shoe heel counter pressure
Retrocalcaneal Bursitis (Haglund’s)	Gentle soleus stretch on flat; avoid aggressive	Any stretch that increases posterior heel pressure	Heel lift; cortisone injection; surgical Haglund’s resection if severe
Plantar Fasciitis (with tight Achilles)	Gastroc + soleus; seated towel stretch	Overly aggressive end-range dorsiflexion immediately post-injection	Night splint; orthotic; plantar fascia-specific stretch (toe extension)

Quick answer:Achilles stretching protocol: eccentric heel drops on a step (3 × 15 reps, 2x daily) are the gold standard for tendon remodeling. Static calf stretch (30-second holds × 3) reduces resting tension. Avoid aggressive ballistic stretching during acute tendinopathy — it loads the tendon in an uncontrolled way. Start eccentric loading under supervision if pain is severe. Call (810) 206-1402.

Tight Achilles tendons are behind more foot and ankle pain than most people realize. In our clinic, we’ve found that a tight gastrocnemius is present in over 60% of patients who come in for plantar fasciitis, Achilles tendinopathy, flat feet, heel pain, and even knee and back problems. The frustrating part? Most patients have been told to stretch, but they’re doing it wrong — targeting only one muscle when two need attention, not holding long enough, or stretching aggressively through pain, which makes tendinopathy worse. This guide gives you the exact protocol we prescribe at Balance Foot & Ankle, including the eccentric loading program that research consistently shows outperforms passive stretching alone for tendon healing.

Achilles Anatomy and Why It Gets Tight

The Achilles tendon is the largest and strongest tendon in the body, connecting the gastrocnemius and soleus muscles of the calf to the calcaneus (heel bone). Understanding the two-muscle structure is essential for effective stretching — they are affected differently depending on whether the knee is bent or straight.

• Gastrocnemius: The larger, more superficial calf muscle that crosses both the knee and ankle joints. Because it crosses two joints, it is only maximally stretched when the knee is fully extended (straight) and the ankle is pulled into dorsiflexion. Tight gastrocnemius is the more common finding — responsible for what the Silfverskiöld test calls “gastrocnemius equinus.”
• Soleus: The deeper, broader calf muscle that crosses only the ankle joint. It remains tight regardless of knee position, so the bent-knee stretch is needed to specifically target it.
• Achilles tendon proper: The combined tendon of both muscles. It has a zone of relative avascularity (poor blood supply) 2-6 cm above the insertion, which is why mid-substance Achilles tendinopathy heals slowly and why eccentric loading — rather than passive stretching — is the treatment of choice for tendon remodeling.

Achilles tightness is perpetuated by modern lifestyle: prolonged sitting shortens the hip flexors and calves together; high-heeled shoes keep the Achilles in a shortened position for hours daily; and running or jumping without adequate warm-up or stretching adds repetitive microtrauma to an already-shortened system. In our clinic, we see this pattern most often in runners, nurses and teachers who stand all day, and desk workers who transition directly to exercise without warming up.

The 7 Best Achilles Stretches

These seven stretches are listed in order of clinical priority — the first two are non-negotiable foundations; the rest add specificity and variety. All stretches should produce a gentle pull sensation, never sharp pain. If you feel sharp pain in the Achilles during any stretch, stop immediately and see a podiatrist before continuing.

1. Standing Wall Calf Stretch (Gastrocnemius)

Target: Gastrocnemius muscle
How: Stand facing a wall, hands on wall at shoulder height. Step the stretching leg straight back 2-3 feet, keeping the heel flat on the floor and toes pointed forward. Keep the back knee fully straight. Lean into the wall until you feel a strong stretch in the upper calf. Do not let the heel rise or the foot rotate outward.
Protocol: 3 sets × 30 seconds, 3× daily (total: 9 sets per day)
Why it works: With the knee extended, the gastrocnemius is maximally loaded and stretched. This is the single most important Achilles stretch and should never be skipped.

2. Bent-Knee Wall Stretch (Soleus)

Target: Soleus muscle
How: Same starting position as stretch #1, but this time bend the back knee slightly while keeping the heel on the floor. You’ll feel the stretch shift to the lower calf, just above the heel. This is a subtler sensation than the gastrocnemius stretch — that’s normal.
Protocol: 3 sets × 30 seconds, 3× daily
Why it works: With the knee bent, gastrocnemius tension is reduced and the soleus is isolated. Soleus tightness is often overlooked and is a major driver of insertional Achilles tendinopathy and Achilles tightness at the heel.

3. Step Edge Calf Stretch

Target: Gastrocnemius and soleus (deeper range)
How: Stand on the edge of a step with only the front half of your foot on the step. Allow your heel to drop below the step edge until you feel a deep stretch throughout the calf. Hold position. For extra gastrocnemius emphasis, keep the knee straight; for soleus, bend the knee slightly.
Protocol: 3 sets × 30-45 seconds, twice daily
Why it works: The step edge allows a greater range of dorsiflexion than standing on flat ground, producing a deeper stretch at the end range of motion where most people are tightest. This is also the starting position for eccentric heel drops (see below).

4. Seated Towel Stretch

Target: Achilles tendon and plantar fascia
How: Sit on the floor or a chair with legs extended. Loop a towel or resistance band around the ball of your foot. Gently pull the toes toward you while keeping the knee straight. Hold the end-range position.
Protocol: 3 sets × 30 seconds, particularly useful first thing in the morning before standing
Why it works: Morning stiffness is caused by overnight contraction of the calf and plantar fascia. Performing this stretch before the first step dramatically reduces first-step heel pain in plantar fasciitis patients and eases Achilles morning stiffness. We prescribe this as the very first thing to do every morning before getting out of bed.

5. Kneeling Achilles Lunge Stretch

Target: Soleus, posterior capsule, Achilles insertion
How: Start in a half-kneeling position (one knee on the ground, one foot flat on the floor). The front foot should be slightly forward. Lean your torso forward, pushing the front knee over the toes, until you feel a stretch deep in the calf and ankle. Keep the front heel on the floor.
Protocol: 3 sets × 30 seconds per side, once daily
Why it works: The kneeling position allows a long stretch of the posterior ankle capsule and soleus simultaneously. Particularly effective for patients with insertional Achilles tendinopathy and Haglund’s deformity where flexibility at the back of the ankle is restricted.

6. Foam Roller Calf Release

Target: Gastrocnemius and soleus fascia (myofascial release)
How: Sit on the floor with a foam roller under both calves. Support your weight with your hands. Roll slowly from the ankle to just below the knee, pausing for 10-20 seconds on any tender spots. For increased pressure, cross one leg over the other.
Protocol: 2-3 minutes per leg, before stretching (not after)
Why it works: Myofascial release reduces muscle tension and fascial restrictions before stretching, improving the effectiveness of subsequent static stretches. This is a preparation step, not a replacement for stretching — foam rolling alone does not produce lasting length changes in tight tendons.

7. Ankle Alphabet / Circles

Target: Ankle joint mobility and proprioception
How: Seated with foot elevated off the floor, write the letters of the alphabet in the air using your big toe as the pen. Alternatively, trace large circles clockwise and counterclockwise, 10 repetitions each direction.
Protocol: Once daily, especially after prolonged sitting or during warm-up
Why it works: Ankle mobility work lubricates the joint, activates proprioceptive receptors, and prevents the stiffness that accumulates with inactivity. Particularly valuable for patients recovering from ankle sprains where residual stiffness perpetuates Achilles compensation patterns.

Eccentric Heel Drop Program — The Evidence-Based Achilles Remodeling Protocol

Eccentric exercises are the most evidence-backed treatment for Achilles tendinopathy — outperforming passive stretching, ultrasound, and most other conservative interventions in randomized controlled trials. The Alfredson protocol (1998, updated with refinements through 2024) remains the gold standard. Eccentric loading stimulates tendon collagen remodeling, reducing pain and improving tensile strength in the chronically degenerated tendon.

Phase	Exercise	Sets/Reps	Knee Position	Target
Weeks 1-2	Heel drop, both legs raising	3 × 15	Straight	Gastrocnemius
Weeks 1-2	Heel drop, both legs raising	3 × 15	Bent (~45°)	Soleus
Weeks 3-6	Heel drop, single leg lowering	3 × 15	Straight	Gastrocnemius
Weeks 3-6	Heel drop, single leg lowering	3 × 15	Bent (~45°)	Soleus
Weeks 7-12	Single leg, add weight (backpack)	3 × 15, twice daily	Both positions	Progressive overload

The key technique detail: Use both legs to raise up onto the toes (concentric phase), then shift weight to the affected leg only for the slow lowering (3-5 seconds down — this is the eccentric phase). The eccentric phase is where the therapeutic benefit occurs. The protocol is designed to work through mild-to-moderate pain (3-5 on a 10-point scale) — this is one of the few contexts where continuing exercise through pain is evidence-backed. Sharp or severe pain (7+) is a stop signal.

Important caveat for insertional Achilles tendinopathy: The classic eccentric heel drop program was designed for mid-substance tendinopathy (pain 2-6 cm above the heel). For insertional tendinopathy (pain right at the heel bone attachment), lowering the heel below neutral on a step compresses the Haglund’s bump against the tendon insertion and makes symptoms worse. For insertional cases, perform the eccentric drops only to the neutral position — not below the step — and avoid aggressive plantar flexion stretches. We always differentiate these two presentations before prescribing the protocol.

When and How Often to Stretch

Timing and frequency matter as much as technique for Achilles stretching. In our clinic, we give patients a specific daily schedule because ad hoc stretching — doing a few stretches when you remember — does not produce lasting tissue length changes. Consistent mechanical load over time is what permanently lengthens a tight Achilles-calf complex.

• First thing in the morning (before getting out of bed): Seated towel stretch, 3 × 30 seconds per foot. This addresses overnight shortening and prevents the painful first steps of plantar fasciitis and Achilles morning stiffness.
• Before activity warm-up: Foam roller calf release (2 min per leg) → standing wall stretch (3 × 30s) → bent-knee stretch (3 × 30s). Dynamic ankle circles after static stretches.
• After activity cool-down: Repeat static stretches (3 × 30s each) when muscles are warm. This is when you’ll make the most range of motion gains — warm tissue responds better to prolonged stretch.
• Before bed: 3 × 30 seconds each, standing wall and bent-knee. Night splinting (ankle held at 5° dorsiflexion) is optional but significantly accelerates results for patients with moderate-to-severe equinus.
• Total daily volume: A minimum of 3 stretching sessions per day produces clinical results. More frequent is better, within the limits of comfort.

The Most Common Achilles Stretching Mistakes

The most common mistake we see is patients stretching only the straight-leg version (gastrocnemius) and skipping the bent-knee soleus stretch entirely — then wondering why they’re not improving. The soleus is equally tight in most patients and is the primary driver of insertional Achilles pain and lower calf tightness. The second most common mistake is holding stretches for only 10-15 seconds, which is not long enough to produce viscoelastic creep in tendon tissue. Thirty seconds is the minimum; 45-60 seconds per set produces better results for very tight tendons. The third mistake is aggressive ballistic stretching — bouncing in and out of the stretch position — which triggers a protective stretch reflex, actually tightening the muscle rather than lengthening it. Always use slow, sustained holds.

Products That Accelerate Achilles Recovery

Frequently Asked Questions

How long does it take for Achilles stretching to work?

Consistent stretching (3× daily, 30-second holds) typically produces noticeable improvement in flexibility within 4-6 weeks and meaningful pain reduction within 6-12 weeks. Chronic equinus that has been present for years may take 3-6 months of dedicated work. The eccentric heel drop program for tendinopathy shows clinical results in 8-12 weeks in research studies, with continued improvement up to 12 months.

Should I stretch a sore Achilles tendon?

For mid-substance Achilles tendinopathy (soreness 2-6 cm above the heel), gentle stretching and eccentric exercises are appropriate and beneficial — the research supports continuing through mild-to-moderate pain. For insertional Achilles tendinopathy (pain at the heel bone), aggressive dorsiflexion stretching can worsen symptoms. After an acute strain or if there is swelling and bruising, rest first and see a podiatrist before stretching.

Can stretching cure Achilles tendinopathy?

Stretching alone is rarely sufficient to resolve established Achilles tendinopathy. The tendon requires active loading (eccentric exercises) to stimulate collagen remodeling and restore tensile strength. Stretching improves flexibility and reduces tension on the tendon, but the eccentric heel drop program is the primary therapeutic intervention. For severe or chronic tendinopathy (>3-6 months), additional treatments like shockwave therapy, PRP, or surgery may be needed.

Is it better to stretch a cold or warm Achilles?

Warm tissue stretches more effectively and with lower injury risk. After activity, when the muscle is warm and pliable, is the ideal time for range-of-motion gains. Cold morning stretches (before getting out of bed) are primarily for managing stiffness and first-step pain, not for gaining flexibility. Foam rolling before stretching helps warm up the tissue even before activity.

When should I see a podiatrist for Achilles pain?

See a podiatrist if: pain is severe (7+ out of 10), if there is sudden onset pain after a pop or injury, if stretching and eccentric exercises haven’t helped after 8-12 weeks, if the tendon is visibly swollen or thickened, or if you cannot bear weight normally. At Balance Foot & Ankle, we offer same-day appointments at (810) 206-1402 in Howell and Bloomfield Hills.

Does insurance cover Achilles tendon treatment?

Most insurance plans cover office visits and standard treatments for Achilles tendinopathy including physical therapy referrals, orthotics (when medically necessary), and surgical procedures. Shockwave therapy (ESWT) and PRP coverage varies by plan. Contact Balance Foot & Ankle at (810) 206-1402 to verify your specific coverage before your appointment.

Frequently Asked Questions

What’s the difference between Achilles tendinitis and tendinosis?

Tendinitis is acute inflammation (early-stage, under 6 weeks). Tendinosis is chronic degeneration without active inflammation — collagen breakdown, microscopic tearing, thickening. This distinction is critical for treatment: tendinitis responds to rest and anti-inflammatories; tendinosis does NOT respond to NSAIDs or ice because there’s no active inflammation to suppress. Tendinosis requires eccentric loading therapy and often PRP to stimulate collagen repair. Many patients treat tendinosis like tendinitis for months, prolonging recovery unnecessarily.

Will Achilles tendinitis lead to a rupture?

Untreated Achilles tendinopathy increases rupture risk — but it’s not inevitable. Risk rises significantly when patients continue high-impact activity through moderate-to-severe pain, or return to sport before the tendon has healed. In our practice, patients who complete a structured eccentric loading protocol have roughly a 3% rupture rate. Those who ignore the condition and keep training have rates closer to 15–20%. Early treatment isn’t optional — it’s rupture prevention.

How long does Achilles tendinitis take to heal?

Insertional Achilles tendinitis (at the heel bone) typically takes longer than mid-portion tendinitis — often 3–6 months with consistent treatment. Mid-portion responds faster, usually 6–12 weeks. The biggest predictor of recovery time is how long you’ve had symptoms before starting treatment. Patients who begin care within 4 weeks recover twice as fast as those who wait 6+ months. Chronic tendinosis can require 12–18 months even with optimal care.

What is eccentric heel drop exercise and does it work?

Eccentric loading — raising on both feet on a step and lowering slowly on the injured foot alone — is the single most evidence-supported treatment for mid-portion Achilles tendinopathy. The Alfredson protocol (3 sets of 15 reps, twice daily, over 12 weeks) shows 60–80% success rates in research. The mechanism: controlled overload stimulates collagen remodeling and tendon thickening. It should be done on a step edge with a heel drop below level — flat-surface heel raises are significantly less effective.

Can I exercise with Achilles tendinitis?

Yes, with modification. Low-impact activity — swimming, cycling, elliptical — is generally well-tolerated and maintains fitness without loading the tendon. Running can often continue at reduced volume (30–40% less) if pain stays below 4/10 during activity. Plyometrics, hill running, and speed work should stop until the tendon is at least 70% healed. The key rule: some discomfort during eccentric exercises is acceptable; sharp or worsening pain means stop.

Should I use heat or ice for Achilles tendinitis?

For acute tendinitis (first 2–4 weeks): ice after activity to reduce inflammatory pain. For chronic tendinosis: heat before exercise to increase blood flow; ice after to reduce post-exercise soreness. Many patients with chronic tendinosis use ice exclusively and wonder why they’re not improving — cold vasoconstricts the tendon, reducing the blood flow that chronic degeneration requires to heal. If symptoms have been present more than 6 weeks, switch your protocol.

What shoes help Achilles tendinitis?

A heel lift of 8–12mm is the most impactful footwear modification — it reduces the mechanical stretch of the tendon during gait. Motion-control or stability shoes work better than neutral shoes for most patients. Avoid minimalist and zero-drop shoes entirely during treatment. Temporary heel lifts (3/8″) added to regular shoes are a quick way to assess whether elevation helps before investing in specific footwear.

What is PRP therapy and does it work for Achilles tendinopathy?

PRP (Platelet-Rich Plasma) involves drawing your blood, concentrating the growth factors via centrifuge, and injecting them into the tendon under ultrasound guidance. For chronic mid-portion Achilles tendinosis that hasn’t responded to 12+ weeks of eccentric exercise, PRP shows 60–75% success rates in systematic reviews. Results take 6–12 weeks to manifest. We use ultrasound guidance for all tendon injections to ensure accurate placement. PRP is generally not covered by insurance but is typically $400–700 per treatment.

Does Achilles tendinitis affect both feet?

Most cases are unilateral (one side), typically the dominant-leg side or the side of greater mechanical load. Bilateral Achilles tendinopathy can occur in runners who dramatically increase training volume, but also warrants evaluation for systemic conditions — particularly fluoroquinolone antibiotic use (ciprofloxacin, levofloxacin are known to weaken tendons), seronegative arthropathies, and hypothyroidism. If both tendons are symptomatic without a clear mechanical cause, a systemic workup is appropriate.

When does Achilles tendinopathy require surgery?

Surgery is considered after 6–12 months of failed conservative management. Procedures include debridement of degenerated tissue, calcification removal (for insertional tendinopathy), and in severe cases, tendon reconstruction with FHL transfer. About 10–15% of patients with Achilles tendinopathy eventually need surgery. The outcomes are generally good — 80–90% return to activity — but recovery takes 6–9 months. We always exhaust shockwave therapy and PRP before recommending surgery.

Is Achilles tendinitis related to plantar fasciitis?

They often co-occur and share common risk factors: tight calf muscles, overpronation, rapid training increases, and inadequate footwear. Mechanically, a tight gastrocnemius (calf) increases load on both the Achilles insertion and the plantar fascia. Treating one effectively often improves the other. If you have both conditions simultaneously, the rehabilitation protocol is similar — eccentric calf work and dorsiflexion stretching address both pathologies.
