Sizing Guide

Last Updated: June 2026

All Rouge Rabbit footwear is sized in UK sizing. Use the guide below to find your perfect fit. If you are between sizes, we recommend sizing up.

How to Measure

Stand on a flat surface and measure the distance from the back of your heel to the tip of your longest toe. Do this in the afternoon when your feet are at their largest. The Rouge 01 runs true to size.

Fit Tips

• Measure both feet — use the larger measurement.
• Wear the socks you intend to pair with the shoe when measuring.
• If between sizes, size up for a more comfortable fit.
• The Rouge 01 features a standard-width last. Wide-foot wearers may prefer to size up half a size.
