One common cause of hammertoe is related to wearing high-heeled style shoes or overly narrow shoes that crowd the toes. The muscles of the toes work in pairs in order to achieve straightening and bending movements of the joints in the toe.
The most common result of a hammer, claw or mallet toe is the development of friction related problems such as corns, callous, blisters and general rubbing and chafing. These hammertoe crest pads help by supporting a bent under toe while easing pressure on the toe tips and reducing the strain on the metatarsal joint.
