Socks on the mat.
Having facilitated thousands of classes watching participants sliding around and fussing with their socks, well, plain and simply, socks can interfere with your connection. They can also make it harder for you to balance, especially if they are ill-fitting. It was hard for a facilitator at an in-person class to see if your feet were properly aligned when they are hidden under loose socks or socks that are sliding off, and you run the risk of injury from slipping if you wear them. Now with online classes, it's very challenging, if not impossible to see what the feet are doing.
Not all socks are treated equally, to keep your body safe, find a pair like the ones pictured here by Toesox, worn by one of our regular clients. They stay put and are pretty too!
