I was injured and intended to use this when walking, but I only used it about three times and no longer needed it, so I'm selling it. I haven't used it much, but it is a used item, so please understand this before purchasing. I threw away the box, so it's not included. You can find instructions on how to put it on by searching online. Brand: ZAMST Size: L Product Use: Achilles tendon protection Use: Heel Target Age: All ages Color: Black
