As mentioned above, the outer calf muscles are the powerhouse of the calf. However, this power also needs to be delivered to the street or the court. This is where the wedge setting comes in. Ideally, the foot rolls off via the big toe, which is the strongest of our five toes and the only one that can really bring our power onto the street. It can be considered something like our traction control. If the big toe is weak or cannot move properly, our traction control is faulty and we end up wasting energy. To prevent this, the wedge setting serves to strengthen and mobilize the big toe at the same time. The wedge setting creates a larger angle of movement for the big toe, which increases the muscular pre-tension and requires its full range of movement.
