  Sizing & Fit Advice

   Fits True to Size (TTS) with an adaptive, locked-in midfoot fit. Runners requiring additional toe-box width should select the Wide (2E) or Extra Wide (4E) sizing variants.

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 usual running/athletic 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:

• Sportstyle / Casual Sneakers: Add +0.5 cm to your measured foot length.

• Performance Running Shoes: Add +0.5 cm to +1.0 cm to allow room for natural foot swelling and toe movement during runs.

Asics Signature Fit & Characteristics

Performance Fit Profile: Asics shoes are engineered for a secure, locked-in fit around the heel and midfoot, while providing adequate space in the toe box for impact protection during foot strike.

GEL™ Cushioning & Support: Built with structured arch support and GEL™ technology, performance models may feel slightly snugger out of the box compared to everyday lifestyle sneakers.
