A heel offloading apparatus including a cushion sized and adapted to surround at least a dorsal side of an Achilles tendon and substantially independently supports and stabilizes an ankle. The apparatus further includes a body for positioning the cushion relative to the ankle. The apparatus is configured to elevate an intended wearers ankle and heel when the intended wearer is wearing the apparatus and lying in a supine position so as to relieve pressure from the heel and thereby prevent formation of heel pressure ulcers.
