Ankle stabilising orthosis that relieves pain related to injuries of the ligaments of the tibiotarsal joint and consolidates the ankle while the sprain heals. It is also indicated in cases of chronic instability, osteoarthritis or even active arthritis. Composed of two lateral calottes joined together by a heel pad, this ankle brace is easily attached to the foot by two straps, one fixed and the other removable according to the patient's morphology. The Velcro fastening system combined with a tightening buckle allows precise and quick adjustment of the shells around the tibia. The foam covering the inner layer of the ankle brace guarantees the patient impeccable comfort, even in the event of sustained physical or sporting activity. The malleolar area, which is generally fragile, is made of a flexible texture that prevents shocks and dampens foot vibrations. Thanks to the thinness of its materials, this ankle brace slips easily into any sports shoe and does not hinder foot movements. Fits both left and right feet.
