New Balance’s Tokyo Design Studio is responsible for some of the brand’s more sophisticated footwear offerings crafted from the highest quality of materials. Essentially two shoes in one, the Niobium Concept 2 is a trail-inspired silhouette that quickly transforms from a sandal to a mule upon removing the detachable heel strap. It features the sole unit from New Balance’s best-selling trail runner — the Fresh Foam Hierro — making it ideal for outdoor use. Designed for comfort, the shoe is outfitted with a buckle fastening system that gives you a locked-in feel, while still allowing you to easily slip it on and off. Below, a Vibram outsole ensures your feet remain gripped to the ground no matter the terrain.
