Size Guide

Choose your shoe size on the product page. The phone scan does not recommend a size. The size you pick is the outline. After you order, the scan shapes the arch on that outline. Use this chart to compare US men's, US women's, and foot length.

US women's sizes are 1.5 sizes above US men's for the same foot length. EU sizes are approximate and calculated from foot length; brands vary, so compare your foot length where you can.

How to measure your foot

  1. Place a sheet of paper on a hard floor against a wall.
  2. Stand on it with your heel touching the wall, wearing the socks you normally wear.
  3. Mark the tip of your longest toe, then measure from the wall to the mark in millimeters.
  4. Measure both feet and use the longer one.

Between two sizes? Choose the larger one. The toe end of the insole can be trimmed for a clean fit.
