The Flexible Filly Air Shock Ankle Boot exterior is designed with Air Cushion Technology, Flexible Concussion Protection with an Offset Strike Guard. 
The raised shape is designed to flex slightly during impact to help reduce the impact force. Underneath is an airbag insert running the length of the tendon. The airbag lies flat in the strike guard space between the inner foam lining and strike guard shell to provide extra protection.
