The New Balance 57/40 RSA sneakers are the answer to a question that is simple, yet astronomical in scale. Despite its legacy of unassuming, almost effortless versatility, the original 574 was a unique design for its era, a hybrid road/trail design that didn't lean on visible technical features. The 57/40 approaches the hybrid concept with a few extra years' worth of design developments to explore, and creates a new perspective on an iconic design. 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.
