Shoes with rocker bottoms can activate underused muscles in the leg and foot, improve balance, and decrease heel and mid-foot pressure. One study suggested that the metabolisms of rocker sole wearers may increase slightly due to increased muscle usage.
The wearer must compensate for the instability of rocker bottom shoes, which causes an increase in muscle activation and better balance over time. Some wearers with heel or mid-foot conditions find that rocker bottoms alleviate pressure on problem areas. Some manufacturers of rocker bottom sneakers claim their shoes can help tone the wearer's legs. Rocker bottom shoes have drawbacks as well, such as an increased likelihood of falling due to the instability of rocker soles.
