The K-Formula is the latest flagship kart boot from Sparco, which has been developed to provide unequaled levels of comfort.

The boots are manufactured from an ultra-light perforated calfskin material upper, which allows for maximum breathability whilst maintaining a soft, comfortable fit.

• Rotary speed lace system for a faster and more precise fit
• Lightweight breathable liner to help reduce perspiration
• Ultra-lightweight calfskin leather upper provides superb levels of comfort
• Thin rubber sole for optimum grip and sensitivity on the pedals

The K-Formula kart boot features Sparco’s very latest elasticated rear bellows, allowing for optimum ankle flexibility and comfort whilst still feeling secure on the foot.

Other top-level features include an ultralight anatomic insole and a new rubber sole that offers unsurpassed levels of comfort and grip, and increased levels of sensitivity through the pedals. A brand new rotary lace-up system allows for fast and secure closure across the entire boot.

The boot also features a reinforced heel, which has been designed to minimize fatigue on the ankle inside whilst being reinforced externally.

These boots are also available, if required, to be fully customized through Sparco’s Infinity project.
