These are the gentlemen's waterproof slip-on shoes that keep feet dry and comfortable in the coldest, wettest conditions--even as low as -20º F. An independent comfort test exposed the shoes to -20ºF for 30 minutes and showed that the shoes' durable 5mm-thick neoprene/rubber blend uppers retained heat, dropping only by 21º F from room temperature. The shoes are 100% impermeable to water, snow, and slush while the four-way stretch neoprene ensconces a foot to provide a secure fit yet slip off easily after a day's walking. The textured soles are made from rubber, providing confident grip in all conditions. Black. Whole sizes 8-12. (1 lb.)
