How to Find Your Size (Step-by-Step Guide)
1. Setup: Place a plain sheet of paper on a hard floor, flushed against a flat wall. 2. Position: Stand on the paper with your heel resting gently against the wall (wearing your preferred socks). 3. Mark: Mark the furthest point of your longest toe on the paper with a pencil. 4. Measure: Measure the distance from the edge of the paper (wall) to your mark in Centimeters (CM).
Recommended Fitting Margin:
Casual / Lifestyle Sneakers: Add +0.5 cm to your measured foot length.
Performance & Running Shoes: Add +0.5 cm to +1.0 cm for comfortable movement and natural foot swelling.
