Jack Wolfskin’s offerings are the least expensive but also the heaviest of the semi-stiff boots reviewed. Unlike the other boots they’re not one-piece leather and have a fabric tongue, which probably explains the lower price. They do have a thick rand round the sole, hard toe and heel bumpers, good cushioning and good grip. The fit is slightly on the narrow side and they’re not quite wide enough for me. The sole has a slight rocker that helps to make walking a little easier. I’d rather more of a rocker though. As with the other semi-stiff boots these are ones for snow and crampons in my opinion.
