Examples of foot care devices include specialized sandals, toe spacers and toe pillows, according to the Health Resources and Services Administration. Many of these devices offload strain from the foot to the device to relieve pain and maintain foot health in people with certain medical conditions.
Foot care devices are often used by people with insensitive feet due to medical conditions such as Hansen's disease. Nerve damage in the legs and feet resulting from poorly controlled diabetes is another common cause of insensitive feet, reports Mayo Clinic. Persons with diabetic neuropathy may benefit from foot care devices such as specialized diabetic socks, according to Healthline.
