Flat feet need all the support they can get.

Supporting your flat feet helps correct overpronation issues and keeps them feeling energized. When you're choosing insoles, only structured support that matches the arch of your foot will do.

Start by choosing your insoles - For extra firm support perfect for most flat feet, try Pace Insoles. For ultra firm support made for especially flat feet and severe overpronators, check out Dash insoles.

Then choose your arch height - select low for feet that are flat when weighted and unweighted or medium for feet that are flat weighted but show an arch when unweighted.

The Reinvention of Over-the-Counter Insoles

Why are these the last insoles you'll ever buy? 3 reasons.

Insoles For Life

Most insoles need to be replaced every six months. What a waste of money — and don’t even get us started on the environmental impact. That’s why we do things differently.

Tread Labs insoles have a unique, two-part design. A molded arch support that lasts forever (okay, up to one million miles), and an interchangeable top cover you can peel off and replace to make your insoles like new again.

Million Mile Guarantee

Did you know the average person walks about 100,000 miles in their life? But we’re not about average. That’s why we guarantee our insoles for one million miles.

So, if they ever break or lose their shape? Just get in touch and we’ll send you a new pair. No questions asked. And if you do walk a million miles? Heck, we’ll send your feet a trophy.

The Height of Comfort

Most over-the-counter inserts are one-size-fits all. We think that’s crazy. Flat Foot Fred and Bella Ballerina in the same inserts? Not if they want their feet happy.

Here’s the reality: Whether you suffer from plantar fasciitis, other foot pain or just want a little extra cushioning, you need insoles that match the contours of your feet. We make it easy with insoles that come in four arch heights - low, medium, high, and extra high. You'll get a semi-custom fit your feet will love.

    "I have very flat feet and plantar fasciitis in my right foot which has been very painful. I've tried an expensive boot from my podiatrist to no avail. I've tried steroids but the pain came back. I'm so happy with Tread Labs. My right foot is pain free. I can actually work out on my treadmill again. I am so happy I made this purchase."

    "I've been looking for insoles for quite some time and Pace insoles are PERFECT. They have excellent arch support for my flat feet and it's noticeable how much less my feet ache after strenuous activity (I play a lot of competitive tennis). I highly recommend these insoles and there's no doubt I'll buy more for my other shoes!"
