The 2026 Sparco K-Rapid WP kart boots are designed for drivers who need dependable comfort and control in wet racing conditions. This waterproof evolution of the K-Rapid keeps your feet warm and dry while maintaining a close, secure fit that supports consistent and precise pedal inputs.
A soft microfibre leather upper is combined with welded seams and a fully integrated waterproof membrane to create a durable, sealed construction that resists water ingress during rain-soaked sessions. The advanced rotor lace closure system uses an internal ribbon to distribute pressure evenly across the entire foot, delivering quick adjustment, secure fitment, and reliable pedal feel. Inside, a supportive footbed and anatomical insole help reduce vibration and fatigue, allowing you to stay focused throughout longer stints.
Built to minimise distraction caused by cold or damp footwear, the K-Rapid WP supports steady concentration and confident control when conditions are at their worst.
