Allbirds to VEJA shoe size
The short answer
Allbirds 5.5 is VEJA 5 or 6 by the two brands' own charts. 4 of 13 Allbirds sizes land on a different label at VEJA.
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.
