The WAFFLE® Heel Elevator Custom surrounds the lower limb in air and is designed to float the heel while sustaining the integrity of the foot and ankle. The air-filled straps and foot pad offer pressure ulcer prevention, treatment and comfort. It can be used conveniently at home and on O.R. tables, stretchers, ICU beds, wheelchairs and general ward beds. This is recommended for prevention and treatment of Stages I-IV Pressure Ulcers and Deep Tissue Injury. It is not a walking boot.
