These fur foot warmers will boost the warmth of any pair boots! Place the warmer against the top of your foot while you're putting on your socks, then put on your boots. They're a great reusable, sustainable and biodegradable alternative to one-time use foot warmers! In my experience they work well at keeping hands and feet warm if they started warm, they are not as good at warming up already cold hands and feet. They are made with offcuts from previous projects so they may have pen marks.
