Reduction of peak pressure on the forefoot with a rigid rocker-bottom postoperative shoe.
An ideal postoperative shoe should be comfortable to wear and protect the foot during recovery from surgery or injury. Protection is assumed to be related to peak pressure and force-time integral under the foot. This study compared a commonly used postoperative shoe with a new postoperative shoe that incorporates a rigid sole with an 11 degrees rocker bottom. The new postoperative shoe significantly reduced peak pressures on the forefoot by 20%. The amount of pressure and force-time integral reduction is compared with other values found in the literature for various shoe modifications. Indications for rocker-bottom shoes are also explored.
