Sorel insulated waterproof boots Model: kinetic breakthru size 7 (in my opinion fits like a 6 with thick socks) I am a size 6, and it fits me perfectly wearing thick socks. I bought these because they’re really nice quality and have such high traction sole. Like most Sorels I have ever owned, I knew to size up because they all run small in my experience. So these are size 7, but in my opinion, fit a size 6 perfectly
