The running shoes of the 1970s might best be described as deceptively simple. While lacking the visible technology and aggressive design of later years, the innovations of the ‘70s would lay the foundation for modern performance. The 237 is a contemporary reinterpretation of ‘70s running heritage that melds a range of heritage design inspirations into one deceptively simple, exceptionally versatile, contemporary silhouette. An EVA midsole, herringbone outsole and streamlined upper offer a classic launching point for modern flourishes like oversized N branding, extended midsole length, and gator inspired foxing and mudguard. You could call the cohesion of the 237’s familiar feel and exaggerated updates the simplest way to make a statement. Meets New Balance's green leaf standard Meets New Balance’s green leaf standard: upper is made of 50% or more recycled content, and/or leather that supports more responsible manufacturing through the Leather Working Group, and at least one midsole/outsole material contains a minimum of 3% bio-based or 5% recycled content.
