Which hiking shoe to choose? Choosing a hiking shoe depends on the type of terrain, weather conditions and the profile of the hiker. First of all, determine the height of the shank and the type of sole.
High upper or low upper hiking shoe? Low stem for short hikes with no difference in altitude, "mid" stem for medium mountains, high stem for long hikes with bag carrying and glacier hikes.
Which sole for a hiking boot? Favour a Vibram sole, which is extremely adherent on dry and wet ground. For mountaineering, choose a so-called "semi-automatic" shoe to which you can attach crampons (Asolo Elbrus GV and Salomon X Alp).
