This is my second pair of UA boots. I only wear them in the summer months. They are the most comfortable boots I have owned and allow for my feet to breath. The biggest problem with them is they seem to come apart easily. I have had this pair for several months and they seem to be in good shape, but my last pair started coming apart at the seams  made the last longer with some shoe goo. I have heard UA is improving them. If your feet get hot easily and you want a comfortable pair, these boots are for you. I'll buy another pair when these fall apart.
