The X-Light is the ultimate ultra-light weight driving shoe. The X-Light is the only racing shoe on the market that features a full stretch fabric upper. This unique fireproof stretch fabric has been developed by the Sparco engineers to be breathable and durable. The X-light stretch fabric wraps around the foot like a second skin and prevents dust, soil or other materials from entering the shoe. Kevlar cables woven into the upper give the right amount of support. This combination provides an extremely comfortable fit, highly breathable and offers a high level of protection. The X-light features a Carbon Fiber sole. The special Carbon Fiber was developed by Sparco Engineers in the Sparco OEM Seating Division. This carbon fiber is unique because it has been developed to be flexible, it is inlayed into the sole and runs from the toes to the heel. Carbon Fiber is visible through the window of the ultra-thin oil-resistant and anti-static sole which offers greater pedal sensitivity. The cushioned inner sole has another unique feature, it has a printed silicon pattern which gives added traction and pedal feel. The X-light is available in five colors in sizes from 39 to 46. X-Light is FIA 8856-2018 approved.
