I live in Brisbane Australia and would not normally need a winter boot like this one but as I am travelling to the US in winter I thought they would be suitable.
I found them to be comfortable but heavy, but that is probably just me not being used to wearing a boot like this.
The reviews said they ran small  and to size up however they are not. I found them to be true to size. Unfortunately I will have to return mine, don't think I will get enough wear from them.
