Not all human bodies are optimal for skating. Many of us are shaped in such a way that the geometry of our hips, legs, or ankles hinders our ability to improve our skating. Ideally, when an inline skater stands in a neutral position, with his body weight centered over their skates, his weight should be evenly distributed across the each foot. On inline skates, this means that they can easily transfer the body weight from one to the other side, and with small movements of the knee instantly apply either edge to steer or adjust a turn or control. But for many speedskaters, this is just not the case. When we try to stand in a neutral position, more of our weight is focused on the inside or outside edge of our feet because of the way our body is shaped. We can have this problem with one foot, or both feet, and the imbalance of weight distribution can go either way – towards the inside or the outside of the foot. On inline skates, these skaters are at a disadvantage because their skate is naturally more on one side. So it's hard to change edges and we must move the knee a greater distance toward the 'high side' to compensate.
