Common Sizing Mistakes
- Buying Air Max Challenge in your AF1 size. AF1 runs about half a size smaller in number. If you wear AF1 in 10, take Air Max Challenge in 10.5.
- Assuming YEEZY 700 V3 sizing translates directly. YEEZY 700 V3 runs about half a size larger in number. If you wear YEEZY 700 V3 in 10, take Air Max Challenge in 9.5.
- Thinking Air Max Challenge differs from AM90 or AJ1. All three round to the same size in the Feetlot model. Same number across Air Max Challenge, AM90, and AJ1.
