Why not opt for a ski booth liner that is perfectly adapted to the shape of your foot? Optimise your performance and increase your comfort and technique with an injected liner. The technology works by injecting a PU mousse into the liner. This moulds perfectly to the shape of your foot, creating a liner that is unique to you, and which provides unbeatable comfort and a great sensation.
