Depends on how far I’m walking in. I don’t like to walk very far with Sorel boots, but they work well. I do put my Ice Breaker boot covers in my pack for a long walk and all day outing, but wear uninsulated boots when I’m walking. One pair of Smartwool socks because wool works even when it gets wet unlike down. I’ve tried those down socks with nylon coverings, but they don’t breathe like wool. Those Ice Breaker covers have zippers that are much quieter than the first ones I used with Velcro closers. Those chemical hand warmers under the toe area work pretty well when it gets really cold. Keeping everything else warm with good clothing helps keep feet warm too to keep good circulation throughout your body.
