Calluses result from constant, gradual pressure or friction to the skin. The skin responds by becoming thicker. Calluses serve as a protective mechanism and need only be addressed if they become excessively large, uncomfortable, cracked, ripped or blistered underneath.

Calluses may appear anywhere on the body. They are more common on hands and feet because these body parts are exposed to the most stress. However, sport-specific equipment may cause calluses elsewhere. For example, figure skaters and skiers often develop calluses on their ankles.

Calluses also develop from equipment that does not fit properly. To assure a proper fit, a complete change of equipment may be necessary. In many instances, auxiliary pads, wedges or donuts can be used to reduce friction from equipment. For more information regarding manufacturing and using a donut pad, see accompanying article/handout.

Not all athletes develop calluses. Those who do should be aware of how to take care of them. Following is a list of suggestions on callus care:

• Keep calluses filed down and smooth with a callus file. Some athletes prefer to do this after a shower when calluses are soft. This should be a daily or every-other-day ritual.
• Keep calluses soft with hand lotion during the day and petroleum jelly at night. Other products that may be helpful include Bag BalmÒ and CoronaÒ ointment.
• If calluses are large or cracking, try an intensive program of sanding and softening. At night, don gloves following the application of petroleum jelly, Bag BalmÒ or CoronaÒ ointment. If this does not help, consult a medical professional such as a certified athletic trainer or your physician.
• If a blister develops underneath a callus, sand the callus and protect the callus/blister with a donut pad to reduce pressure. DO NOT ATTEMPT TO DRAIN THE BLISTER. The blister can become infected very easily. If you notice redness, increased temperature or increased pain around the blister, consult a medical professional.
• PREVENTION is the key to callus care. Proper fitting equipment, daily sanding and moisturizing of calluses should prevent most problems.
