Handmade in Portugal, the 4_01 Trainer is a technical and refined running-inspired silhouette that combines durability, style, and performance. It takes on a sleek all-black upper that is made using high-abrasion ripstop nylon with bonded overlays to withstand the wear and tear of metropolitan and outdoor environments, while a Vibram® outsole ensures that you have adequate traction on uneven terrain. The sole is made using a combination of EVA foam and rubber which ensures a balance of support, shock absorption, and a responsive feel.
