The approach shoe is not going to walk up to you by itself. Rather, an approach shoe is one that will help you approach that mountain top with greater ease. It is actually a shoe designed with a special grip on the sole that is meant to aid rock climbers on the trail back and forth from the climbing area.
Supination is not a shoe or a shoe feature. Instead it's an action that can be done by the foot. It is when, during walking or running, the outermost part of the heel touches the ground as it's supposed to, but instead of rolling inward, like in a normal walking pattern, the pressure stays on that outside part of the heel. This causes pressure on the smaller toes and the lateral side of the foot. To help with this problem, supinators (those who walk or run with supination) can try neutral running shoes.
A blucher is a shoe that features two side flaps of fabric or other material. These two materials feature lacing to hold them together. For instance, many tennis shoes feature the blucher style, as can dress shoes and even boots. In other words, many, or even most, shoes that contain laces display this style.
