I got these boots for my son for Christmas and he was super satisfied to finally have a warm boot that fit.  They seem heavy until you put them on, he was surprised that they seemed much lighter on his feet.  We live in the midwest and it gets below zero a lot...the main reason for purchasing these.  Altho we haven't had that cold of weather yet, these boots seems to be what he needed to stay warm.  The Seller is very cooperative as well.  I ordered these in November and asked if i could possibly exchange them if the size was incorrect and they had no problem with that.  The sizes are what they should be and there was no problem with what I had ordered.  I would 100% recommend these boots and this seller.  Can't go wrong with either!
