The K1 RaceGear GTX-1 racing shoe was developed in cooperation with top pros from our K1 Athlete program. The feedback from this development program has enabled us to incorporate unique features in this shoe to make it a universal choice for drivers across multiple segments of Motorsports. The GTX-1 is a mid-top design constructed with soft calf skin leather and strategically placed perforated vents for superior comfort and breathability. The lightweight, pre-formed rubber sole is designed to offer drivers excellent pedal feel without sacrificing durability. An integrated Achilles Flex Zone allows for unimpeded mobility and maximum comfort. Another feature of the GTX-1 is our full canopy tongue that is strategically attached to the inner base on each side of the shoe, wraps the entire surface area of the drivers foot and is lined with soft knit Nomex. This unique feature ensures the safety of the drivers feet as well as keeping the inside of the shoe clear of all dirt and debris.Features: SFI 3.3/5 Rated (SFI 5) Constructed of premium leather for superb comfort & durability Pre-Formed textured rubber sole for maximum grip & pedal feel Achilles Flex Zone for mobility Unique Canopy Tongue for added protection and cleanliness Available from Youth Euro 33 to Adult Euro 48Product Description: Racing Shoe, GTX-1, Driving, Mid-Top, SFI 3.3/5, Leather Outer, Nomex Inner, Black / Gray, Size 4, PairPit Stop USA offers K1 RaceGear GTX-1 Nomex Shoes - Black/Grey - Size: 4 24-GTX-N-4 at low everyday prices.
