The Running Shoes of the 70s Are Simple, But Only In Appearance. Although lacking the technology and aggressive design of modern sneakers, the innovative features of that decade are the precursors of today's lines. The 237 is a contemporary reinterpretation of the classic running shoes of the 70s, and fuses the inspiration of classic design with a silhouette in appearance simple, although exceptionally versatile and current. The Eva Midsole, the Spike-Shaped Sole and the Aerodynamic Instep constitute the canvas where to capture the modern elements, such as the oversized > brand, the extended midsole and the protections and mottling inspired by crocodile skin. The familiar look of the 237 along with its extravagant touches are the easiest way to set trends.
