These are my new favorite no-show socks. They really stay put! I wore them during a full day of touring Versailles (my phone says I traveled 9 miles) and did not have to adjust my socks at all. They have more rubber at the back than most and it really works to keep a grip on your heel.
These are slightly no show, closer than some of the other I’ve tried. The problem is one of them hurts the back of my foot. I really wanted to take them off by the end of the work day. Going to keep looking for better ones!
