Dealing with winter weather, particularly snow and slush, can be tough for standard sneakers. With the TDS Niobium Concept 3, New Balance and Snow Peak have transformed the beloved 580 into a versatile snow boot. The upper is made from an eco-conscious, waterproof eVent material that offers protection from the elements. Inside is a removable bootie featuring Primaloft padding that provides added warmth and has a lightly textured base for independent indoor wear. When inside the outer shell, the Vibram-produced, 580-inspired outsole instills confidence on slippery surfaces with pronounced lugs.
