If you love getting outdoors whatever the weather, slip your foot into the Icebug Speed-L BUGrip boot. This women's waterproof winter sport boot is made from a combo of ripstop nylon, synthetic nubuck and Protec PU overlays for added durability and scuff protection; the wraparound, non-stretch heel strap improves stability, as a breathable BUGdri membrane keeps moisture out. Backed up by a supportive ESS shank, the plush OrthoLite insole can be removed and replaced with a personal orthotic. Comfortable to four below, the Icebug Speed-L BUGrip ankle winter boot is equipped with a rubber outsole imbedded with 16 carbide-tip studs for sure traction over icy surfaces.
