FITDeveloped around the idea of a racecar fit, the Vapor features a new V16 last, which is designed to engage the major metatarsal by shaping the outsole to the natural contours of your foot. This allows the metatarsals to sit lower in the boot while the big toe is slightly raised, increasing flex across the joint and allowing you to generate maximum power when sprinting off the mark.Constructed with a Teijin synthetic upper, the Vapor features a tongue less construction to wrap the foot for a snug fit, while the internal anti-skid sock liner eliminates any movement within the boot.TOUCHTo enhance your touch and feel, the Vapor features a new 3-D textured Speed Rib construction to ensure high-speed control. Applied with Nike’s All Conditions Control (ACC) Technology, the Vapor’s upper provides consistent levels of grip on the ball in wet and dry weather conditions.TRACTIONA full length Tepex glass fibre chassis makes the Superfly V extremely lightweight. Designed for use on soft natural ground surfaces, the outsole features six aluminium screw in studs for the best possible traction.
