The few socks tested were likely tested in static conditions, without movement because it's easier. But a foot is always in motion, so we've recreated a model capable of replicating the movement of the lower leg. We also conduct tests on real cyclists to verify the results. With these socks, you can save 2 watts at 50 km\/h.\u003cbr\u003e\n\u003cbr\u003e\n Product Features\u003cbr\u003e\n Castelli's Fast Feet project, for pedaling even in hot conditions.\u003cbr\u003e\n The foot part is inspired by the Castelli Rosso Corsa sock for maximum comfort inside the shoe\u003cbr\u003e\n Polyurethane strip at the back to keep the sock in perfect position\u003cbr\u003e \nThe leg part is made of Lycra with grooves designed to facilitate the flow of air\u003cbr\u003e\n\u003cbr\u003e\n Color: Black.\u003cbr\u003e\n\u003cbr\u003e\n Size chart:\u003cbr\u003e\n S\/M = 36-39\u003cbr\u003e\n L\/XL = 40-43\u003cbr\u003e\n 2XL = 44-47","brand":"CASTELLI","offers":[{"title":"L\/XL","offer_id":55794488050038,"sku":"4523029 010--L\/XL","price":27.71,"currency_code":"EUR","in_stock":false},{"title":"XXL","offer_id":55794488082806,"sku":"4523029 010--XXL","price":27.71,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0913\/2979\/0326\/files\/4523029-010-0-1.jpg?v=1750238981","url":"https:\/\/animasportiva.com\/en\/products\/castelli-fast-feet-2-sock-4523029-010","provider":"Anima Sportiva","version":"1.0","type":"link"}
