Put a sheet of paper against a wall. Stand with your heel touching the wall and mark the tip of your longest toe. Measure from the wall to the mark. Do both feet at the end of the day (feet swell) and go with the longer one, then match it to the chart below.

Then match that number to the size chart — it runs from 9.2 to 11.0 inches, with US men's, US women's, UK and EU equivalents.

Go up. You want your toes to spread and grip — not press against the front.

Actually wide. The most common complaint about other barefoot shoes — even the big names — is that they still pinch your toes. Ours are built to let your foot splay out flat, the way it's meant to when it carries you.

It's the simple week-by-week wear schedule that comes free with every pair. It starts you with short, low-impact wear and builds from there, so your feet get stronger without getting overloaded. It's the difference between rebuilding and flaring up.

It can — if you rush. That's the whole reason the Ground Plan exists. You start slow and build up, so your feet strengthen instead of flaring. Going gradually isn't a nice-to-have here; it's the point.

Rebuilding strength takes time, not days. Plenty of people describe meaningful change over a few weeks to a few months — everyone's feet are different. The 90-day guarantee is there so you can give it a real run without gambling money on it.

Bring the Ground Plan to them. This isn't about ripping support away overnight — it's a gradual strengthening approach, and we genuinely want you to involve your clinician, especially if your case is severe. Ground Theory shoes aren't a medical device and aren't meant to diagnose or treat any condition.

The gradual approach is built exactly for people who can't just switch overnight. You go at the pace your feet can handle — that's what the Ground Plan is for. If you have a diagnosed condition or you're unsure, check with your clinician first, then ease in slowly.

Wear them on concrete. Wear them in the rain. Wear them for full shifts once the Ground Plan has you there. If they don't hold up over ninety days of that, email us and we'll refund you — worn, scuffed, whatever state they're in, and you don't ship anything back.

On whether they last: ninety days is long enough to find out. Wear them on concrete, on trail, in the rain. If they don't survive that, they were never going to survive year one, and you get your money back either way.

No. They look like a normal sneaker — no goofy toe-pockets. Wear them on shift, on errands, out in public, not just the gym.

Your Roam 2.0 and the Ground Plan (the week-by-week transition guide).

Hand wash, cold water, mild soap, and let them air dry. That's it.

Pull the insoles out and wash them separately. Use a soft brush on the outsole if the tread has picked anything up.

What to avoid: the washing machine, the dryer, and drying them on a radiator or in direct sun. Heat is what breaks down the adhesive holding a shoe together, and it'll shorten their life faster than anything you do on your feet.

They're everyday shoes, not water shoes — fine in the rain, not made for wading or submersion.

Orders leave within 1–3 business days. Because each pair is prepared to order, delivery usually takes 10–15 business days after that.

Yes — you'll get a tracking link by email the moment your order ships. You can also follow it anytime from the Track Your Order link at the top of the site.

Wear them and follow the Ground Plan. If you're not happier on your feet within 90 days, email us and we'll refund you — no hard-sell, no hoops. You've already been burned enough; the risk on this one is ours, not yours.

Email support@groundtheoryshoes.com with your order number and whether you want a refund or a different size.

You don't ship the shoes back. Worn returns are accepted and there's nothing to package, no label to print, and no return shipping to pay.

Refunds go back to your original payment method once approved, usually within 3–5 business days depending on your bank.

If you need a different size, say so in the same email and we'll get the right pair out to you.

Fair — you've heard it all before. That's exactly why there's a 90-day guarantee instead of a louder promise. You don't have to believe us. You just have to give your feet a real chance, and if it's not for you, you're covered.
