Common outsoles are rubber or dual-density constructions with textured, non-skid treads to improve grip. Many use oil- and slip-resistant rubber compounds, and some snow-boot listings add ice spikes or aggressive lugs for extra traction on ice and packed snow.
Durability features listed include tempered steel shanks for added support, double-row and all-around welt stitching, multi-layer sole systems, reinforced stitching, support panels, and internal support spines in activity boots.
Listings describe sealed waterproof construction and waterproof membranes placed beneath the upper; some of these membranes are noted as breathable. Other entries list waterproof synthetic uppers such as synthetic leather and nylon.
Uppers include full-grain leather, genuine suede, and waterproof synthetic materials such as synthetic leather and nylon.
Lining options include neoprene and polyester and fleece linings; some boots use removable EVA foam liners. One listing also notes a faux-fur collar and insoles with activated carbon for odor control.
Insoles include EVA and polyurethane. Listings mention removable 5mm EVA footbeds, dual-density polyurethane footbeds with heel stabilizers, and cushioned polyurethane insoles with odor-control features.
Widths reported include medium and wide. Some snow-boot descriptions note a medium width and advise selecting your regular size and rounding up on half sizes.
