X TDS Niobium Concept 1 Three-In-One Boots

New Balance's Tokyo Design Studio and skiwear label Snow Peak collaborate on a new capsule collection that includes these innovative khaki-beige Niobium Concept 1 boots, inspired by the sole of the former's MT801 trail running trainers and named after the 41st element of the periodic table. They're crafted from rubber and mesh as a waterproof boot with eVent technology that can be turned into a sandal or an indoor slipper.

• Rubber, mesh and fabric

A classic on the sportswear scene that started out selling arch supports to police officers and waiters in the early 1900s, New Balance has re-emerged as a fashion must-have in recent years and, with stylish collaborations from J.Crew to Stone Island, the iconic sneakers are going nowhere.
