New Balance’s 57/40 approaches their iconic 574 silhouette with a fresh point of view and a willingness to experiment. Where the original 574’s go-anywhere versatility was the result of a design that blended road and trail features, the 57/40 combines the familiar with a series of exaggerated features inspired by the bold technical running designs of the ‘80s and ‘90s. An overall sleeker silhouette provided by a slimmer last combines with a range of exaggerated features. The unique midsole combines a flared take on the classic 574 construction with ‘90s tech inspired details, while the mudguard and eyerow feature the distinctive wavy embellishments of the ‘80s.
