Toe Toasters are the ultimate in convenience & comfort, and an eco-friendly alternative to plug-in, heated boot bags. Microwave these seed-filled "socks" for 2 minutes on HIGH, then slide them into your boots. Toe Toasters will pre-heat your boots for 30-40 minutes* (between your house and the hill - or wherever your adventure takes you) . Remove them from boots, replace with your own two feet, and enjoy a warm, comfortable boot-up! YOUR TOES WILL THANK YOU!
