Sum's socks are super nice! Very beautiful designs and great aesthetics - a great change from other running socks. They are good at moisture wicking, and stay in place, and no blisters at all. I'm training for a half marathon, and I'm using these for all my training sessions so far. I am wearing them with Hoka trainers and I find them quite hot inside the shoes, but I think this is more about the shoe than the sock. Would reccomend
