The Primaloft insulation in these boots is no joke—my feet stayed warm

Emily ★★★★★ Sep 14, 2026

Sat in a stand for six hours at 15°F and my toes never went numb, which honestly never happens with my old boots. The BOA dial is easy to adjust with gloves on, and the Gore-Tex kept my feet dry crossing a slushy creek bottom. Best money I've spent on gear in a while.

Wore these through a full day of freezing slush and my feet stayed completely dry and warm, the Gore-Tex membrane really does its job. The BOA lacing is a game changer with thick gloves on, no more fiddling with frozen laces.
