Nike to lululemon men's shoe size
The short answer
Nike 13.5 is lululemon 13 or 14 by the two brands' own charts. 2 of 16 Nike sizes land on a different label at lululemon.
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.
