3D-Custom Fit Sock

Right after you order, we email you simple instructions to scan your feet with your phone (it takes a few minutes). We print a test shell of your exact fit from that scan and ship it within 1–2 days. You wear it, send us photos and notes, and we refine the design until it's right. Only then do your boots go into production.

Yes — buy a Fit Sock pair and the full $145 you paid is credited toward your first Prevolve boot order. The fit sock is effectively free when you go on to order boots.

A printed test of your fit catches pressure points, width issues, and shape inconsistencies before anything is manufactured. Since the fit sock became a standard step, fit remakes have dropped from roughly 1 in 7 pairs to about 1 in 40.

A pair confirms both feet — most athletes' feet differ slightly, and both boots are printed individually. A single (from $45) works if you mainly want to feel the fit before committing.

That's the point of this step. Tell us what you feel, we adjust the design, and we can send a revised fit round before production begins. Nothing gets built until you approve the fit.

Your boots move straight into production using the confirmed geometry, and your scan stays on file — future pairs and accessories print from it, and returning customers get 25% off reorders on an existing scan.
