What does a podiatrist treat?

Podiatrists specialize in the foot, ankle, and lower leg. They diagnose and treat heel pain, bunions and hammertoes, tendon injuries, nerve conditions (Morton's neuroma, neuropathy), toenail disorders, skin conditions (warts, calluses, ulcers), fractures, sports injuries, diabetic foot complications, ankle instability, and perform foot and ankle surgery. At Balance Foot & Ankle, Dr. Tom Biernacki DPM, Dr. Carl Jay DPM, and Dr. Daria Gutkin DPM AACFAS serve Howell, Bloomfield Hills, and surrounding Michigan communities.

How often should a healthy person see a podiatrist?

Annual foot exams are beneficial if you are over 60, are an active runner or athlete, have diabetes, have a family history of foot problems, or notice any changes in foot shape, nail appearance, or skin texture. Preventive visits catch problems early — before bunions require surgery or a small nail issue becomes an infection.

Can foot problems cause knee, hip, or back pain?

Yes — the foot is the foundation of the kinetic chain. Overpronation causes the tibia to internally rotate, increasing stress on the knee and altering hip alignment. High arches transmit shock poorly, overloading the ankle and knee. Custom orthotics that correct foot mechanics frequently improve knee, hip, and back symptoms — one of the most underappreciated benefits of podiatric care.

When should I see a podiatrist versus an orthopedic surgeon?

Podiatrists specialize exclusively in the foot, ankle, and lower leg — making them the most experienced providers for most foot and ankle conditions. For foot and ankle surgery, a DPM with high case volume is appropriate. Dr. Tom Biernacki at Balance Foot & Ankle has performed over 3,000 foot and ankle procedures. Call (810) 206-1402.

What causes smelly feet?

Foot odor (bromodosis) results from the interaction between sweat and bacteria that naturally colonize the foot's skin — the foot contains approximately 250,000 sweat glands per square foot, the highest density of any body area, producing up to half a pint of sweat per day. The odor mechanism: sweat itself is odorless — it is primarily water with small amounts of salt, urea, and fatty acids; the odor is produced when bacteria on the skin metabolize the sweat components; the primary bacterial culprits are Brevibacterium linens (which produces isovaleric acid and methanethiol, the same bacteria that give certain cheeses their pungent smell), Corynebacterium species, and Staphylococcus epidermidis; bacteria thrive in the warm, moist, oxygen-deprived environment created by socks and closed shoes — these conditions favor bacterial overgrowth and intensified odor production. Why some people have worse foot odor: hyperhidrosis (excessive sweating) — the fundamental driver of severe bromodosis; primary hyperhidrosis (idiopathic excessive sweating) affects approximately 2–3% of the population and dramatically increases the bacterial food source; diet — foods containing sulfur compounds (onions, garlic, spicy foods, alcohol) produce volatile compounds that are excreted through sweat; stress and anxiety — the eccrine sweat glands on the feet are activated by emotional stimuli through the sympathetic nervous system; hormonal changes — puberty and pregnancy dramatically increase sweating; closed, non-breathable footwear — synthetic materials trap moisture; footwear that is not alternated and dried between wearings accumulates bacteria; fungal infection (athlete's foot) — tinea pedis adds a different, musty odor component to bacterial odor; aged or worn socks that retain bacterial contamination despite washing.

What are the most effective treatments for foot odor?

Foot odor treatment targets the underlying mechanism — reducing sweat production, eliminating bacteria, and creating an environment hostile to microbial overgrowth — and is highly effective when the approach is consistent and multi-pronged. Hygiene — the foundation: thorough daily washing of the feet with soap, paying particular attention to the interdigital spaces (between the toes) where bacterial density is highest; drying completely after washing — especially between toes; moisture between the digits is the primary bacterial habitat; washing feet before bed reduces the overnight bacterial colonization that accumulates in socks. Antiperspirants for the feet: regular underarm antiperspirants (containing aluminum chlorohydrate or aluminum chloride) applied to clean, dry feet — particularly the soles and between the toes — reduce sweating directly at the eccrine gland level; applying at night before bed (when sweating is reduced) maximizes absorption into the sweat duct; this is the single most underutilized and effective intervention; clinical-strength antiperspirants (Certain Dri, Drysol prescription) provide greater efficacy for hyperhidrosis; aluminum chloride hexahydrate 20% solution (Drysol) is the prescription-grade treatment — applied under occlusion (plastic wrap) overnight for maximum effect; typically 2–3 initial treatments per week, then maintenance. Antibacterial soap: chlorhexidine gluconate (Hibiclens) or triclosan-containing antibacterial wash reduces the bacterial burden on foot skin; use daily or every other day; benzoyl peroxide foot wash (5–10%) has antibacterial activity and controls odor effectively. Footwear strategies: alternate shoes daily — at minimum every other day — to allow complete drying; moisture absorbs into the insole and upper and requires 24+ hours to fully dry; use cedar shoe inserts, silica gel packets, or antimicrobial shoe sprays in shoes between wearings; replace insoles every 3–6 months. Socks: moisture-wicking synthetic materials (Dri-FIT, CoolMax, merino wool) outperform 100% cotton — cotton absorbs and retains moisture against the skin; change socks if they become damp.

Can foot odor be permanently cured?

Foot odor can be dramatically reduced and kept under control with consistent management, but 'permanent cure' in the absolute sense is not achievable for most people because the underlying biology (eccrine sweat gland activity and skin bacterial colonization) is intrinsic to normal physiology. What is permanently treatable: the severity of odor can be reduced to socially undetectable levels with the right combination of hygiene, antiperspirant, and footwear practices; most people with even severe bromodosis achieve excellent control with consistent management; specific identifiable causes (fungal infection, hyperhidrosis requiring medical treatment) can be definitively addressed. Medical treatments for persistent hyperhidrosis-driven foot odor: iontophoresis — passing a gentle electrical current through water in which the feet are submerged; the electrical current temporarily blocks eccrine gland secretion; 20–30 minute sessions performed 3–4 times per week initially, then weekly maintenance; highly effective for palmoplantar hyperhidrosis (affecting hands and feet simultaneously); devices are available for home use after an initial in-office trial; approximately 80% of hyperhidrosis patients achieve significant reduction; botulinum toxin (Botox) injections: injected into the plantar foot skin to block acetylcholine-mediated eccrine gland activation; extremely effective — 90%+ sweat reduction; lasts 4–9 months before repeat treatment is needed; plantar injections are painful (nerve block required); requires office visits every 6–12 months for maintenance; laser treatment: microwave-based and laser devices that ablate eccrine gland ducts (similar to MiraDry for underarm hyperhidrosis); developing evidence base for plantar use; endoscopic thoracic sympathectomy: surgical interruption of the sympathetic nerves controlling plantar sweating; generally considered excessive for foot odor alone given surgical risk; reserved for severe, refractory palmar hyperhidrosis where foot improvement is a secondary benefit.

Does athlete's foot cause foot odor and how are they related?

Athlete's foot (tinea pedis) and foot odor (bromodosis) frequently coexist and each can worsen the other — but they have distinct causes and require different treatments, and addressing only one while ignoring the other produces incomplete results. How tinea pedis contributes to foot odor: fungal infection adds a distinct musty, yeasty odor component to the normal bacterial foot odor; the fungi (primarily Trichophyton rubrum and Trichophyton mentagrophytes) metabolize skin proteins and lipids, producing volatile compounds with a characteristic smell; the macerated, scaling, broken skin produced by tinea pedis between the toes creates ideal entry points for bacterial overgrowth — the combination of fungal and bacterial colonization in the interdigital spaces produces more intense odor than either alone; the moist, scaling skin environment of active tinea pedis provides an even more favorable habitat for odor-causing bacteria than normal skin. How bacterial overgrowth predisposes to tinea pedis: the moist, bacteria-dense interdigital environment compromises normal skin barrier function, making fungal colonization easier; excessive sweating that drives bacterial odor also provides the warm, moist environment that promotes fungal growth; the relationship is bidirectional. Distinguishing tinea pedis from other causes of interdigital odor: tinea pedis has characteristic signs: scaling, peeling, or maceration between the 4th and 5th toes (most common location) or on the plantar arch (moccasin pattern); itching is prominent — more so than in simple bromodosis; a KOH skin scraping under microscopy confirms fungal hyphae. Treatment strategy when both are present: treat the fungal infection first with topical antifungal (clotrimazole, terbinafine, miconazole) twice daily for 4 weeks; simultaneously address bacterial odor with antibacterial wash and antiperspirant; keep the interdigital spaces meticulously dry (hair dryer on low setting after bathing is highly effective); once tinea pedis is cleared, the odor component it contributed resolves; ongoing prevention of recurrence is essential — the same environments that caused the original infection are likely still being frequented.

How to Get Rid of Smelly Feet Permanently (Podiatrist Method)

Quick answer: Smelly feet (bromodosis) is caused by bacteria + sweat + occlusive shoes. Dr. Tom Biernacki, DPM’s permanent fix combines hygiene, antibacterial spray, breathable footwear, and treating pitted keratolysis if present. Most patients see results in 2-3 weeks.

Dr. Tom Biernacki DPM — Smelly Feet Treatment — Dr. Tom DPM explains the smelly feet permanent fix on YouTube

The Real Cause (It’s Not Sweat — It’s Bacteria)

Sweat itself is odorless. The smell comes from bacteria — primarily Kytococcus sedentarius and Corynebacterium species — that feast on the keratin and sweat trapped in your shoes. They release isovaleric acid (the smell of strong cheese) and propionic acid (the vinegar smell).

If you also see tiny pits or craters on the bottoms of your feet, that’s pitted keratolysis — a related infection that makes the smell 10x worse. Treating that is the key to permanent resolution.

The Permanent Fix (5 Steps)

Wash daily with antibacterial soap — Hibiclens (chlorhexidine) or Dial Antibacterial. Lather 30 seconds, scrub between toes
Dry thoroughly between toes — moisture = bacteria fuel. Use a separate towel
Antibacterial spray on shoes — Lysol or Clinical Strength Lotrimin daily for 2 weeks
Switch to moisture-wicking socks — merino wool or CoolMax synthetics. Cotton holds sweat
Rotate shoes every 24-48 hours — never wear the same pair two days in a row. Lets them dry fully

If The Smell Doesn’t Stop in 3 Weeks

Persistent odor + tiny pits on the soles = pitted keratolysis. This is a bacterial skin infection requiring prescription topical antibiotic — typically erythromycin gel or clindamycin lotion for 2-3 weeks. I prescribe this in-office during a 15-minute visit.

If you sweat excessively even when not active (hyperhidrosis), the answer is iontophoresis (low-voltage water bath) or Botox injections to shut down sweat glands for 4-6 months at a time.

FAQ

How long until smelly feet stop after starting treatment?

Hygiene + spray = 5-7 days for most. Pitted keratolysis = 2-3 weeks of topical antibiotic. Hyperhidrosis = immediate with Botox, 2-4 weeks with iontophoresis.

Does soaking feet in vinegar help?

Mildly. Acetic acid lowers skin pH and inhibits bacteria — but it’s slower than topical antibiotic. Use 1:4 vinegar:water for 15 min, 3x per week.

Are smelly feet a sign of diabetes?

Sometimes. Diabetic neuropathy can cause increased foot sweating. If you’re newly experiencing smelly feet plus numbness or tingling, get checked for diabetes.
