Silicone heel cups and cushions are designed to mimic the plantar fatty padding on the heels. Best used for elderly patients where the fat pad under the heel diminishes after the age of 70 years. Also very helpful in populations that genetically have less fatty padding on the sole of the feet. Not useful for heel pain for plantar fasciitis or Achilles tendinitis. See corrective orthotic of Achilles tendinitis and arch support orthotic for Plantar fasciitis.
