Fit scenarios

Between sizes: Start with the advice above, then confirm with the between-sizes / half-size guide.
Width: Length and width are separate — see wide feet / narrow fit.
Break-in: Plan for stiff leather or structured lasts — boot break-in sizing.

Width: Medium-narrow tennis last â€” snugger than Superstar forefoot
Break-in: Leather softens modestly

Summary

Adidas Stan Smith is one of the easier classics to size: most guides land on true to size for average feet. It sits narrower than Superstar, so wide feet may prefer half up rather than guessing from a Superstar size-down.
