A waterproof version of the K-Prime boot which keeps your feet warm and dry in wet races while giving you a close and secure fit that supports consistent pedal control. A soft microfiber leather upper, welded seams, a waterproof membrane and a rotor closure system with an integrated ribbon work together to deliver a hard-wearing, sealed construction with even pressure across the whole foot.

Below are the key features and benefits of the boot, giving you a clear understanding of how each element supports your performance on a race kart:

Soft microfiber leather upper: A durable synthetic leather forms a supple yet hard-wearing outer layer that withstands repeated use, helping you maintain long-term comfort and giving you a reliable surface that copes with wet conditions to support consistent control.

Welded seams: Heat-bonded seams remove stitch points that would otherwise allow water to pass through, giving you a sealed construction that helps keep your feet dry and reduces discomfort so you can stay focused through longer stints.

Waterproof membrane: A fully integrated barrier sits between the outer and lining to block water ingress, helping you maintain warm and dry feet during wet sessions and supporting steady concentration without the distraction of cold or damp footwear.

Elasticated inner breathable anti-bacterial lining: A stretch lining links directly to the upper and rear bellows to create a close internal fit that moves with your foot, helping reduce friction and maintaining fresh, comfortable conditions inside the boot so you can concentrate on pedal work.

Rotor lace system with integrated ribbon: A dial-based mechanism tightens an internal ribbon across the entire foot rather than only the upper section, giving you quick fitment with secure and even pressure for improved comfort and reliable pedal feel.

Shock absorbing footbed: A cushioned mid-layer dampens impact loads and vibrations passed through the kart chassis, helping reduce fatigue in your feet and giving you steadier comfort and control during longer sessions.

Anatomic insole: A shaped footbed supports the natural contours of your foot to improve weight distribution, helping reduce fatigue and giving you steadier control during longer sessions.

High grip rubber sole: A textured sole compound provides dependable traction on damp kart pedals, helping transmit subtle inputs with accuracy and giving you consistent pedal sensitivity in wet conditions.

Firm heel box with abrasion-resistant sections: A reinforced heel structure and protective panels around the heel, nose and sides increase durability, helping maintain stability and protecting the boot from wear during frequent kart entry and exit.

Cold and wet feet in prolonged rain can distract you from consistent pedal work, the waterproof build of the boot helps you maintain steady focus by keeping moisture out. The sealed microfiber leather upper, welded seams and waterproof membrane work together to block water ingress so you can stay comfortable through each stint. The secure closure from the rotor system supports precise pedal inputs by maintaining an even hold across your foot. The shaped insole and shock-absorbing footbed help reduce strain as the session progresses, supporting stable control throughout wet events.

The waterproof construction and secure closure give you dependable comfort and control during wet races. Choosing this boot allows you to maintain dry feet and steady pedal feel for consistent performance in poor weather.
