The N45 is designed to keep you cool on a sunny city trail or on dry desert rocks. The construction allows for breathability and abrasion resistance, while recraftable Vibram® soles with traction lugs and Megagrip save you from slips. Featuring ultralight and durable nitrogen-infused EnduroFoam midsoles, the N45 has a high-energy return that feels like you’re walking on air.
