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