Always with the fur side touching your skin, match the shape of the warmers to the tops of your feet over your toes. Begin by putting your socks half over your foot and pushing the warmer down to your toes, then pulling the rest of the sock up holding the warmer down in the sock.
These warmers work best with snug-fitting socks and preferably a wool blend so there is both stretch and something for the leather to grip to. Adjust the fit with your fingers. They can also be inserted into socks and adjusted from the outside to fit.
Your body heat is stored within the fur and circulated back to your feet. This passive warming system does an incredible job of holding a comfortable temperature, keeping you warm but not too hot. We highly recommend the regular and thick for optimum warmth, slim for use in very tight footwear.
