Frequently Asked Questions

How long do I have to return Tread Labs insoles?

You get 90 days under the Our Fit Guarantee, and insoles can be returned in any condition, including trimmed or worn, for a full refund with US return shipping covered by Tread Labs. A prepaid return label is emailed to you, so there's no cost or hassle in sending them back if they aren't the right fit.
 

Is the return policy different for sandals and shoes? 

Yes. Sandals must be returned within 30 days in new, unworn condition, since used sandals aren't accepted back. Shoes can be returned or exchanged within 30 days as well, even if you've worn them, though they still need to be in new, unworn condition to qualify.
 

What does the Million Mile Guarantee actually cover?

It covers the molded arch supports specifically, replacing them for free, no questions asked, if they ever break or lose their shape. Foam top covers aren't included under this guarantee, since they're designed to be replaced periodically as part of normal use.
 

Can I trim my insoles to fit my shoes and still return them? 

Yes, trimming new insoles to fit your shoes doesn't affect your ability to return or exchange them within the 90-day window if you end up unsatisfied.
 

Is there a minimum order for free shipping? 

Yes, free standard US shipping applies to orders over $50, which covers the majority of single insole purchases already, given that most models fall in that price range.
 

Are Tread Labs insoles FSA or HSA eligible?

Yes, Tread Labs accepts FSA and HSA cards at checkout, which lets you use pre-tax health spending dollars toward insoles rather than paying out of pocket.
 

Is there a discount for military members or a first order?

Yes, Tread Labs provides a standing discount to verified military members, and new customers can typically get a set dollar amount off their first order by signing up for the email newsletter.
 

Saving Guide

Try before you commit, since the return window is unusually generous:

Because insoles can go back in any condition, even trimmed or worn, within 90 days with shipping covered, there's little financial risk in testing a pair against your actual daily mileage before deciding they're right for you.

Sign up for the newsletter before your first order:

New subscribers typically receive a set dollar discount on their first purchase, along with early notice of flash sales and seasonal promotions that tend to appear around holidays.

Use FSA or HSA funds if you have them:

Since Tread Labs accepts both at checkout, paying with pre-tax health spending dollars is effectively a discount on top of any promo code, particularly useful given that insoles addressing plantar fasciitis or overpronation often qualify as eligible medical expenses.

Replace top covers instead of buying a whole new insole:

Because the arch support is the part covered by the Million Mile Guarantee and top covers are designed to be swapped out, refreshing a worn pair by replacing just the cover is typically cheaper than purchasing an entirely new insole once the arch support itself is still in good shape.

Reach $50 to unlock free shipping automatically. 

Since most individual insole models are priced close to or above that mark already, a single pair typically clears the threshold on its own, but bundling an extra top cover into the same order guarantees it.

Checklist before you check out: 

Confirm your order clears the $50 free shipping threshold, sign up for the newsletter if this is your first order, check whether you can pay with FSA or HSA funds, and remember sandals and shoes need to stay in new condition if there's a chance you'll return them, unlike insoles.
