PUMA to ASICS men's shoe size

The short answer

PUMA 10.5 is ASICS 10.5 by the two brands' own charts. 0 of 18 PUMA sizes land on a different label at ASICS.

At least one of the two brands publishes no foot length, so the rows line up the US size both charts print. Treat it as the label conversion, not a fit.

Every PUMA size read across to ASICS. US men's sizes on the left, US men's on the right.

Tinted rows change label or sit between two sizes. Read from the two charts only; no formula and no averaging.

What wearers say

Charts describe a garment, not a fit. We do not collect fit reports for this category yet, so this table is the two brands' own claims and nothing more.
