Size & Width Guide

Two minutes with a piece of paper saves most returns. Measure first, then convert, then check the per-product fit finder.

How to measure your feet at home

  1. Tape a sheet of paper to a hard floor against a wall. Measure in the evening, when feet are largest.
  2. Stand with your weight on the foot. Mark the back of your heel and the tip of your longest toe.
  3. Measure heel-to-toe in inches for length, and across the widest part (the ball of your foot) for width.
  4. Do both feet and use the larger one. Add about 1/8" to 1/4" of toe room.

Understanding width: M, N, W, and WW

Width is measured across the ball of your foot and matters as much as length. A shoe that fits in length can still pinch if the width is wrong, and sizing up only adds length, not real room.

Letter Width Who it's for
N Narrow Slimmer feet that feel loose across the ball.
M Medium (standard) The default width most shoes are built in.
W Wide Feet that feel tight across the ball in standard widths.
WW / XW Extra wide The widest fit, with the most room across the forefoot and toes.

Still between sizes?

  • Lifestyle sneakers: size up a half size for a touch more room.
  • Wool or knit shoes: your usual size is usually right, since the upper stretches.
  • Wearing orthotics or thick socks: choose a removable-insole style and consider a wide width for depth.
