This is not a winter boot. The nordaTM 001 G+Spike has a G+ (Graphene) membrane and carbide spikes for increased thermoregulation and traction in winter conditions. Graphene is powered off your heat. As you warm up, it regulates your foot temperature while remaining highly breathable. Carbide steel spikes permanently embedded in the soleplate allow for exploration in inhospitably slick conditions. Part of our 2022 Winter Toolkit. Winter trail running starts here. Photo @payette
