Onitsuka Tiger to Karhu men's shoe size
The short answer
Onitsuka Tiger 13.5 is Karhu 13 or 14 by the two brands' own charts. 1 of 13 Onitsuka Tiger 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.
