Castelli 6 Fast Feet Booties

Castelli 6 Fast Feet Booties If you’re looking to shave off those precious milliseconds during on your next race then the Castelli 6 Fast Feet Booties are the perfect accessory for you. As part of Castelli’s Rosso Corsa range; these booties have been proven to deliver a whopping six watt saving at 45kmph; in comparison to wearing a regular sock. These booties are designed to be zipped over your shoes and calves; and have been refined in a wind tunnel to ensure maximum efficiency. They are crafted from a silicone-coated stretch fabric; which has been primed to streamline the airflow; while the ankle features a grooved Lycra® design that helps to detach the air altogether. Additionally; these booties are held securely in place with flat polyurethane tape at the top; ensuring that they won’t let you down during a race and could very well make the difference between victory and defeat.
