What matters, the researchers conclude in their review, is comfort. In one study from 2001 (overseen by Dr. Nigg), researchers asked soldiers to try six shoe inserts, which varied in terms of cushioning, arch height, heel shape, thickness and other variables. The soldiers were asked to pick the one insert that felt the most comfortable to them and wear that insert inside their shoes during their subsequent military training. A separate group of soldiers wore standard footwear as controls.
After four months, the soldiers wearing the shoes fitted with inserts that felt comfortable to them had a much lower incidence of injury than those wearing standard shoes.
