When it comes to anything that rides on water, surface area equals buoyancy and buoyancy is your friend. The X-Caliber combos are designed with maximum buoyancy for easy ups and effortless cruising, and an improved sidecut allows for better edge-hold and maneuverability.
The X-Cal is now packaged with the Cruise boots for a huge boost in comfort and support. The Cruise uses the lower profile of high-end slalom boots but with a low cuff, so it's easy to get on and off.
