High-performance construction meets long-wearing comfort in the Rossignol X10 Skate Boot. With a committed race fit, the X10 is designed for competitive athletes and expert, high-fitness recreational skiers alike. Rossignol opted for a 3D-injected, soft-touch cuff, so while the X10 isn't quite as light as Rossi's World Cup models, it allows racers and recreational athletes to have top-notch performance without shelling out World Cup dollars. Otherwise, the X10's features, like the same high-performance, low-profile X-Celerator sole, are comparable to Rossignol's World Cup racing boots. The X10 features a polyester thermo-adjustable liner, so you can customize its shape and volume around your specific foot shape, while asymmetrical lacing provides a precise, enveloped fit for ultimate comfort and control. The boot is a step up from the more recreational X8 boot and is the top of Rossignol's Performance lineup. It allows for a natural foot roll and optimum kick amplitude while skate skiing and is ideal for advanced skiers who enjoy long days of training while pushing the limits of their equipment.
