Have, taken as a replacement for my old BW combat boots ankle boots these boots. Business I have sometimes run quite a bit and get a lot of stairs. Therefore me these boots come in handy. Although they are firm, but at the same time very easy, so that one is not for the umpteenth stage breathless or sometime has knee pain. In short form: light and stable. But should be ordered one size larger than normally. Otherwise I have shoe size 47 1/2. Here suits me the boot is almost like a second skin.
