Felt wool and waxed nubuck leather on the surface, waterproof Gore-Tex membrane and a Partelana wool blend liner - plus proper steel studs for grip. The newest addition to the Fennia-awarded felt boot lineup by Pomar! - "H last" - regular Pomar last, somewhat spacious - High quality steel studs, 15 per shoe - Pomar Spike sole with EVA rubber and durable steel studs - Zipper and stretch panels for easier on and off - Detachable insoles - Made in Europe *Note!* Do not wear indoors: the studs are deceptively slippery on smooth stone flooring surfaces, and cause damage to many floors.
