How Feetlot Computes These Numbers
Every New Balance 327 sizing recommendation on Feetlot is the output of a global offset model fit to over 100,000 owner-reported shoe records. Each shoe gets a single number — its "size offset" — that captures how its sizing drifts relative to a reference shoe (the Nike Air Force 1). The result: sizing advice that holds up no matter how unusual a wardrobe is.
