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.
