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 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:
Casual / Lifestyle Wear (e.g., Samba, Gazelle, Stan Smith): Add +0.5 cm to your measured foot length.
Performance Running / Athletics (e.g., Ultraboost, Adizero): Add +0.5 cm to +1.0 cm for comfortable movement and toe clearance during long runs.

Adidas Signature Fit & Characteristics

Fractional EU Sizing System: Adidas uses a unique fractional European sizing system. Always rely on your foot measurement in CM for exact sizing match.
Fit Profile: Classic heritage models (Samba, Gazelle, Campus) tend to have a sleeker, slightly narrow profile, while performance models featuring Boost or Lightstrike foam provide an adaptive, locked-in wrap around the midfoot.
