On to Onitsuka Tiger shoe size

The short answer

On 8.5 is Onitsuka Tiger 25 or 25.5 by the two brands' own charts.

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 On size read across to Onitsuka Tiger. US women's sizes on the left, CM / JP on the right.
