Lifestyle sneakers use different lasts than performance shoes — even within the same brand. Model-level fit beats a generic "Nike runs small" rule when buying Air Force 1 vs Pegasus.
No single answer — Converse Chuck Taylor often needs a larger starting size, Nike Air Force 1 is usually true to size, and Vans Old Skool is close to true to size. Always check the specific silhouette; our model pages list the fit offset and width availability.
Material matters, but it should not override the model verdict. Leather uppers such as Stan Smith or Air Force 1 can start firm, while canvas and knit uppers can stretch or collapse differently. Use the model page first, then treat material as a comfort caveat.
