Today is my 29th day on the Camino Frances, loving it all the way. A few years ago on the Appalachian Trail in eastern U.S. I discovered the wondrous world of toe socks. The brand I use is Ingingi. I'm not a gear tester and have no interest in the company. But as a 65 year-old chubby guy, I do believe they have made my Camino much more enjoyable by eliminating problems with my feet. They have a liner style with which you use another cover sock, and a heavier style. Hopefully this is helpful!
