An Achilles heel pad is an elastic band or sock that one wears on the foot to keep it somewhat immobilized and help control pain. It slips on over the foot like a sock and fits the contours of your foot, ankle, and calf. It works similarly to an ace bandage but it is much easier and convenient to put on and take off.
It allows for limited flexibility of the ankle and foot so that you can still walk effectively and get on with your day, but it prevents the painful Achilles tendon from being flexed too far in any direction and incurring any further damage. It allows the tendon to heal more quickly and reduces pain.
If you are suffering from Achilles tendinitis, it can be quite beneficial to wear an Achilles’ heel had. I can personally attest that it made more of a difference than I thought it would when the doctor insisted that I wear one.
It works well especially at night while you’re sleeping because it keeps your foot almost completely immobilized and allows the tendon to heal itself more quickly that way. It is less effective during the day when you are walking.
They can be worn inside the shoe if preferred, and are easily removable for showers and cleaning. Some of them are coated with mineral oils and other ointments which claim to soothe the affected area. The pad I used to not have that so I cannot be to that.
