The Ultimate Elastic Ankle Support has been specifically designed utilising a seamless circular knit to provide compressive support to unstable ankles and assist with rehabilitation and recovery from load related pain or moderate ligament and tendon injuries. Although thinner than neoprene the compressive design of the support offers a high level of support and is ideal for those who are allergic to, dislike the bulk and/or heat generation of neoprene and latex. The breathable compressive four-way stretch of the material targets support to the area's most requiring it, mimicking the support and action planes of key ligaments and tendons to reinforce them. The compressive element also stimulates blood flow which can help prevent the build up of lactic acid during and post activity. This reduces the prospect of cramp and stiffness whilst also being a valuable recovery and rehabilitation tool to injury. Recommended for: weak, stiff or aching ankles.
