Flex Rating (1 Soft - 10 Stiff) – 7-9, stiffer for the more advanced rider

Flex Control System – Removable tongue stiffeners allow riders to custom tune their boot flex. Keep them both in for maximum support, use just one to provide either increased lateral or medial response, or remove them entirely for a softer flexing boot. Over the course of a season as your boots soften up you can add the tongue stiffeners back in, giving them new life.

Instep Flex Zone – Allows for more forgiving medial flex and natural articulation while maintaining lateral support.
