I did many research & reading of different boots reviews because I wanted to invest in something that would last me and that was actually warm. I’m a school crossing guard so I’m outside in the cold, snow, rain.. you name it. My issue was my toes was always cold to the point of pain, even with 3 socks!! I was previously wearing UGG adirondack and they were horrible for standing in the cold. My job requires me to be outside for 5 hours or more and so far these boots are amazing they are warm, not the warmest but way better than the others. Super comfy too! Like walking on clouds, oh and so light weight as well.On really cold days I can either wear 1 pair of socks (heat holders original) or 2 regular socks and not be in pain from the cold.I’m a size 8-8.5 depending on the brand so I purchased the 8.5 to be on the safe side and I’m glad I did. I have enough room for thick and multiple socks.I will update again if anything changes but so far it’s great!
