The product kept my feet warm and dry in two feet of snow even at -20 to -30 temperatures with wind chill, talking North Dakota cold. The only issue is there is a lot of space for your calves and the upper part is semi flexible so it feels a little loose even zipped up. It is a great boot for a simple pull on thojgh if you arent doing anything major, otherwise you should opt for a strapped boot or a laced boot that has a tighter fit. Would definitely consider buying another pair in the future if needed again.
