Why Pregnancy Changes Your Feet
Medically Reviewed by Dr. Tom Biernacki, DPM — Board-Certified Podiatrist, Balance Foot & Ankle Specialists, Michigan. Last updated April 2026.
Pregnancy produces profound physiological changes that affect the feet in multiple ways. Weight gain — typically 25–35 pounds over the course of a full-term pregnancy — dramatically increases the load on foot structures accustomed to a different baseline. Hormonal changes — particularly the increase in relaxin, a hormone that loosens ligaments to prepare the pelvis for delivery — have systemic effects on ligamentous laxity throughout the body, including the foot. Fluid retention from increased blood volume and altered sodium-water balance produces generalized edema that is most pronounced in the feet and ankles. The cumulative effect of these changes makes foot discomfort one of the most common pregnancy complaints, affecting up to 50% of pregnant women.
Edema: The Most Visible Pregnancy Foot Change
Lower extremity edema during pregnancy results from multiple mechanisms: the expanding uterus compresses the inferior vena cava, reducing venous return from the legs; increased blood plasma volume raises hydrostatic pressure in the capillaries; and reduced albumin concentration lowers oncotic pressure, allowing fluid to shift from blood vessels into surrounding tissues. The result is the characteristic ankle and foot swelling that most pregnant women experience — particularly in the third trimester, in hot weather, and after prolonged standing.
Normal pregnancy edema is symmetric, soft, non-tender, and worsens with heat and prolonged activity. It resolves significantly overnight with leg elevation. Concerning edema — sudden onset, severe, or accompanied by headache, vision changes, or upper abdominal pain — should be evaluated immediately as it may indicate preeclampsia.
Managing Pregnancy Edema in the Feet
Graduated compression socks (15–20 mmHg) are safe throughout pregnancy and dramatically reduce fluid accumulation in the feet and ankles. They should be put on before getting out of bed in the morning, before edema accumulates. Foot elevation above heart level for 20–30 minutes during rest periods throughout the day enhances venous return. Reducing sodium intake moderately helps manage fluid retention. Regular low-impact exercise — walking, swimming — maintains circulation and reduces edema better than sedentary rest.
Arch Changes and Flatfoot Development
Relaxin-mediated ligamentous laxity during pregnancy allows the plantar fascia and supporting ligaments of the foot to stretch under increased body weight. Studies using foot pressure analysis and digital photoplethysmography demonstrate measurable decreases in arch height in a majority of women during pregnancy — changes that partially reverse post-partum but may not fully resolve, particularly after multiple pregnancies. Women who were already at risk for flatfoot (hypermobile joints, pre-existing mild flatfoot) are at greatest risk for clinically significant arch collapse.
Arch collapse during pregnancy contributes to plantar fasciitis, posterior tibial tendon strain, and the posterior leg and arch pain that many pregnant women attribute generically to ‘pregnancy discomfort.’ Supportive footwear with genuine arch support — avoiding flat shoes, flip-flops, and completely unsupported footwear — is the most important preventive measure. Over-the-counter arch support insoles are helpful; for women with significant pre-existing arch issues, custom orthotics provide superior support.
Heel Pain and Plantar Fasciitis
Plantar fasciitis is the most common specific foot diagnosis during pregnancy, affecting an estimated 10–15% of pregnant women. The combination of increased body weight (loading the plantar fascia), relaxin-induced ligamentous laxity (reducing the passive support structure of the arch), and foot pronation (increasing fascia tension) creates a perfect storm for plantar fascia inflammation at the calcaneal insertion. Classic symptoms — sharp first-step morning heel pain — are identical to non-pregnancy plantar fasciitis but may develop more rapidly given the compounding hormonal and mechanical factors.
Treatment during pregnancy prioritizes conservative modalities: supportive footwear worn immediately upon arising (never walking barefoot on hard floors), over-the-counter or custom arch-supporting insoles, regular calf and plantar fascia stretching, and nighttime dorsiflexion splints. Corticosteroid injections are generally avoided during the first trimester and used cautiously in later trimesters; low-level laser therapy and therapeutic ultrasound are safe alternatives available from physical therapists. NSAIDs are contraindicated during pregnancy.
Shoe Size Changes During and After Pregnancy
Research consistently shows that arch collapse and foot ligamentous laxity during pregnancy produce a permanent increase in foot length and width for many women — typically half a shoe size but occasionally a full size. This change is most significant during a first pregnancy and tends to be smaller with subsequent pregnancies. Women should have their feet professionally measured during pregnancy and plan for possible footwear updates post-partum. Continuing to wear pre-pregnancy shoes that are now too narrow contributes to bunion formation, hammertoe development, and metatarsalgia.
Safe Footwear During Pregnancy
The ideal pregnancy footwear has a firm heel counter (prevents heel collapse), minimal heel height (below 1 inch — this is not the time for heels), adequate width across the forefoot to accommodate swelling, adjustable closures (laces, velcro, or elastic) to accommodate edema fluctuation, and a cushioned midsole. Slip-on shoes without adjustable closures may become too tight by afternoon as edema peaks. Walking shoes and supportive casual sneakers meet these criteria; fashion flat shoes and sandals typically do not.
When to See a Podiatrist During Pregnancy
Foot pain that interferes with normal walking or daily activity, heel pain that does not improve with supportive footwear and stretching within 2–3 weeks, numbness or tingling in the feet (which may indicate tarsal tunnel syndrome from edema compressing the posterior tibial nerve), or rapidly developing severe edema all warrant evaluation. Podiatric care is safe throughout pregnancy; we use only pregnancy-safe treatments and work in coordination with your obstetric provider to ensure appropriate management.

In Our Clinic
In our Balance Foot & Ankle clinic, the typical plantar fasciitis patient is a 40- to 60-year-old who noticed sharp heel pain on their very first steps in the morning or after sitting at a desk. Many arrive having already tried cheap shoe-store inserts and a week of ice without relief. On exam, we palpate the medial calcaneal tubercle, check for a positive windlass test, and rule out Baxter’s neuropathy and calcaneal stress fractures. Most of our plantar fasciitis patients respond to a custom orthotic + eccentric calf loading + night splinting protocol within 6–12 weeks — without injections or surgery.
