Nike to Arc'teryx shoe size
The short answer
Nike 9 is Arc'teryx 9 by the two brands' own charts. 0 of 17 Nike sizes land on a different label at Arc'teryx.
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.
