Ice-Vibe® Circulation Therapy is a combination of cooling and massage therapy to effectively process inflammation whilst stimulating repair of ligaments and tendons, allowing for a faster recovery. Ice-Vibe does what Ice cannot. Inflammation is a critical part of the repair process. Icing constricts the blood vessels and restricts blood flow to the injured area, delaying the healing process. Ice-Vibe boots are designed to gently cool the tissue to reduce swelling, but not remove inflammation completelely. This set includes 2 knee wraps, 2 cold packs, 2 panels and 1 charger.
