Ultimate Mid-height Fracture Boot For Foot and Ankle Injuries – VACOped Short is the shorter and lighter version of the VACOped. Thanks to the integrated VACO12 technology, the orthosis adapts perfectly to the foot and ankle. VACOped Short allows not only immobilisation of the ankle, but also a defined range of motion (ROM) from 15° of dorsal extension to 20° of plantar flexion.
