How Adidas and Nike actually compare
Adidas and Nike publish nearly identical size charts, so your Adidas number is usually your Nike number. 67 inches), and Nike lists its men's US 10 at exactly the same length. 69 inches). The main confusion arises from the EU scale.
Adidas uses increments like EU 44 2/3, while Nike rounds to halves, so EU labels appear different even when the fit is consistent. One notable point concerns Nike: 27 of the 210 Nike models tracked by Sizely tend to run about a half size large. If purchasing one of these models, sticking with your Adidas number provides the extra room. When uncertain, rely on your measured foot length.
