Best Waterproof Hiking Shoes for Flat Feet (2026)
Hiking shoes with the stability, arch support, and structure flat-footed hikers need to control overpronation. Not medical advice.
Flat feet and low arches tend to roll inward with every step, and a soft, unstructured shoe just lets that happen - hello, sore arches and tired ankles. The fix is structure: a supportive arch, a stable and stiff-enough midsole, and a secure heel that keeps your foot controlled on uneven trails. Below are the waterproof hikers that deliver it, plus room for orthotics if you use them.
Not medical advice. We review footwear, not feet. If you have foot pain or aren’t sure about your arch type, see a podiatrist or physical therapist. Pair any shoe here with the arch-support insole your clinician recommends.
For arch-pain specifically, see our plantar fasciitis picks; for roomy fits, our wide-feet roundup. Away from the trail, our best waterproof running shoes roundup applies the same arch-support and stability test to a lighter shoe.
How we picked
We prioritized stability and structure - a supportive arch, a stable midsole, motion control, and a removable insole for orthotics - then held every shoe to our standard five-criteria test below.
How we test waterproof shoes
Every pick is scored on the same five criteria and cross-checked against real owner feedback - so the ranking reflects how a shoe holds up, not its spec sheet.
Waterproofing
How well it seals - GORE-TEX, eVent, or a quality liner, with gusseted tongues and taped seams.
Traction
Outsole compound and lug pattern, and real grip on wet rock, gravel, and slick mud.
Support
Midsole stiffness, torsional rigidity, and stability on uneven ground and under a pack.
Comfort
Fit and width options, cushioning, break-in, and weight over long days.
Durability
Upper toughness, toe and heel protection, and how it holds up season after season.
Best overall stability

Frequently asked questions
What hiking shoes are best for flat feet?
Flat-footed hikers usually do best in shoes with real structure - a supportive arch, a stable and torsionally stiff midsole, and a secure heel that controls excess inward roll (overpronation). A removable insole is a plus so you can add a supportive or custom orthotic.
Do flat feet cause overpronation?
Often, yes. Low or collapsed arches tend to roll inward more with each step, which can strain the foot and ankle on uneven trails. Stability-oriented, structured shoes help limit that excess motion.
Should flat-footed hikers use orthotics or aftermarket insoles?
Many do. A supportive arch insole (over-the-counter or custom) can make a big difference. Every shoe here has a removable factory insole, so you can swap in what works for you.
Are stability shoes better than neutral shoes for flat feet?
For many flat-footed hikers, yes - a structured, stable platform (like Oboz's supportive molded insole or KEEN's stiff shank) controls motion better than a soft, unstructured shoe. But fit and comfort still come first.
Is this medical advice?
No - we review footwear, not feet. Flat feet and foot pain are best assessed by a podiatrist or physical therapist. Treat this as a starting point for stable, supportive, waterproof options, and pair any shoe with the insole your clinician recommends.
