Bought these boots last year but had to get new ones because mine were stolen! I was out in minus 25 when I feel through an ice hole up to my knees while walking on the lake. My feet did get wet from the water going over the boot line BUT, during the 6km walk back to my truck my feet stayed warm! I thought I would be losing my toes for sure! Once my boots thawed out enough to get them off, I rung out the liners and used them the rest of the day. Even being wet the were still warmer and more comfortable then any other boots I have ever owned. Thank you for a great product.
