These UGGs are very comfortable and warm, shearling feels nice on bare feet and it is very good at blocking snow from getting into the shoe. But not only that, they connected the left channel together with the right one to pretend both speaker are working (only one actually works). Wish they had more colors in my size. I also love the needles that are provided because they help me work faster. who knows??) So if youre looking for a speaker to begin with. My daughter usually wears a 10, and has only just moved in to this size in other shops, however having read all of the other reviews about the small sizing I ordered a size 11 and size 12 to try. This is a first. I have been using a 2amp battery to power it and have only had to recharge it twice in the month or so that I have owned it. Like mentioned above, the customization is unrivaled, even on headsets twice this price. Theyre extremely warm which I normally shy away from because I tend to run a little warm myself, but these are actually a comfy warm.
