The Luigino Vertigo Q4 Boot offers a unique fit concept not seen in traditional derby boots. Microfiber uppers are backed with leather board counters that are AquaTech moldable to get a perfect customized fit. The microfiber liner works with the Pro Evolution Footbed to achieve an anatomical molded fit, unlike flat like traditional boots. The Barefoot Technology allows a snug, yet comfortable fit that maximizes power transfer and overall performance. Poron padding throughout the boot provides added security, protection, and durability.
