New Balance to Karhu shoe size

The short answer

New Balance 11.5 is Karhu 11 or 12 by the two brands' own charts. 2 of 14 New Balance sizes land on a different label at Karhu.

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 New Balance size read across to Karhu. US women's sizes on the left, US women's on the right.
