William ★★★★★ Oct 14, 2026

Walked through slush and wet snow for two hours and my feet stayed completely dry, which the Gore-Tex lining clearly earns its keep on. The BOA dial is easy to tighten with gloves on, though it took me a bit to get used to the feel. Warmest boots I've owned for late-season hunts.

Ruby ★★★★★ Oct 13, 2026

Sat in a frozen treestand for four hours and my toes never went numb, which honestly never happens with my old boots. The Gore-Tex lining keeps the slush out completely, and the BOA dial is easy to crank down with gloves on.

Wore these for six hours in single-digit temps and my toes stayed warm the whole time, which never happened with my old pair. The Gore-Tex lining actually breathes, so no swampy feeling after the hike out.
