Once you wear wool socks, it’s hard to wear anything else! I’ve worn smart wool for about 7 years; they are my favorite sock even in summer with tennis shoes. Many no-show socks are made of thin cheap cotton that absorb a lot of sweat and wear out quickly. Wool socks protects feet from blisters and reduce odors because the fabric wicks moisture. They’re great... I’ve bought them for my mom and brother. Big fan!
