Xelero Size & Fit Guide
Men’s & women’s US sizes · Letter widths · Fit varies by style
Find your Xelero fit with Xelero’s own style notes and standard US sizing — or stop in for a Brannock fitting at our Kettering, Ohio store.
How it fits
Xelero’s fit varies by style. Xelero says the Genesis II fits true to size, while customers say the Genesis XPS runs small — order ½ size larger.
Xelero’s Custom Fit System includes a second removable 3mm insole you can take out for added width or to make room for custom orthotics.
Xelero uses standard US sizing. The sizes and widths available for each style are shown in our size picker.
Widths
| Width | Women | Men |
|---|---|---|
| Standard | B | D |
| Wide | D | 2E |
| Extra wide | 2E | 4E |
Some Xelero styles show their widths as M and W in our size picker. M is standard width (women’s B, men’s D) and W is wide (women’s D, men’s 2E).

Foot lengths follow the standard US (Brannock) scale, since Xelero doesn’t publish its own chart. Sizes shown are the range we carry: women’s 6–12 and men’s 8–14.
How to measure
- Place a sheet of paper on a flat floor (tape it down so it doesn’t slip).
- Stand with one foot firmly on the paper.
- Mark the tip of your big toe and the back of your heel, then measure between the marks.
- Repeat with the other foot. If your feet are different sizes, use the larger measurement.
