YakTrax Toe Warmers (10 pack)
Ten pairs of foot warmers with adhesive. These are great in ski boots and many of us use them when coaching or skiing. To use, open the package and give them access to the air for ten minutes until they start to feel warm, then peel off the backing and stick them to the top of your socks.
Disposal: the ingredients are odourless and environmentally safe so the warmers can go into your household garbage.
