A little thin for this time of year but I’m not too worried about that. I have plenty of cold weather socks. These are my first pair of toe socks and they do take a little getting used to but I really like them. Since they are my first pair I wanted to try the company that invented them They fit my feet and toes perfectly without any discomfort around seams or anywhere else. I wear a 12 shoe and bought a size large. I will likely buy more in the warm months.
