UPDATE: Its been 3 months since we bought them. We live in the UP so we are normally buried in snow but this year have not had hardly any until recently. These have been great for wearing around town, to school, etc. But now that we've finally got snow and a lot of it the toes of the liners are constantly soaking wet. I have to keep checking them to make sure my sons not going out with wet boots. I dont see a crack, theyre hardly worn so i dont know where the snow is getting in. The entire liner isn't wet just the toes and the inside near the toes. They look like new still. We will be going back to bread bags for the rest of this winter and will order new next year. As much as I love Kamik boots i wont be ordering them for him again. I dont have time or money to waste on boots that wont keep his feet warm and dry. Such a bummer.We love Kamik! We ordered these for my 7 year old. I needed a boot with removable liners so they're earsier to dry. He is a size 13 or 1 depending on the brand, 1 being a little big. I ordered a 1 hoping they would be a little big. They are not! I would say they run a little small. They fit but definitely won't fit at all next year. He has a regular width foot. We don't find them to be too narrow as other have stated. They are very warm and well made. Will order them again next year! They must have good arch support because it took a while for him to get used to the bump in the arch. He loves them now.
