The Luigino Challenge is a low-profile boot that gives maximum performance for all types and styles of inline speed skating. Made with Thermafiber, Microfiber lining, and Carbon Fiber, and all with AquaTech Technology, the Luigino Challenge boot gets the perfect fit, every time. This boot is fully heat moldable to your foot. It also has BFT (BareFoot Technology) for maximum comfort while skating. The Vertical Mounting slots secure the frame to the boot, you’ll never know the bolts are there because of the high density sole padding on top of them! Closed-cell ankle padding is part of this boot and works to reduce blisters while breaking in boots. Luigino’s Nano Buckle is attatched to this boot to ensure that this boot does not slip or come off during use.
