This is a product I purchased when I fractured my ankle. I used it for about a month and a half after surgery when going out. Basically, I wore the black cover (please see the photos) when outdoors. The bottom of the cover is worn and has a hole. *If you don't need it, please let me know and I won't include it. There are also two insoles (white plates/please see the photos). These are placed on the bottom inside the boot to control the degree of ankle bending restriction. Please ask if you have any questions. Brand: AIRCAST Size: M Intended Use: Both feet Target Age: Adult Color: Gray Features a durable semi-rigid shell that supports and protects the foot and ankle. SoftStrike technology absorbs shock, and a lightweight, lab-tested rocker sole promotes natural walking. Overlapping dual air cells line the shell, providing intermittent pneumatic compression to reduce edema three times faster. Breathable, refined open-frame design. Non-marking, non-slip rubber tread enhances traction and wear. Universal fit allows the AirSelect to be worn on either the left or right foot. Inflation pump: TPU (Thermoplastic Polyurethane)
