Their Phoenix boot has become part of my collection. I was hesitant to wear boots, I hadn't worn boots for 3 years, yet I live in Colorado in the mountains, it gets very cold and snowy. (-20 F sometimes). For those days when it's insanely cold outside, these boots have been incredible, they are warm and I can still feel my feet. Aja, my partner, loves them, they are as comfy as barefoot boots get!
