But the Castelli Fast Feet 4 Sock has the development and testing to back up the claim. The few socks that have been tested have probably been tested with a static, nonmoving test because it's easier. But a foot is always in motion, so we created a jig that replicates the movement of the lower leg. And we tested it on actual riders to verify the results. This sock can save 2 watts at 50 km\/h. The newest version has an updated cuff fit for more comfort and aerodynamic gains.\u003c\/div\u003e\n\u003cdiv class=\"paragraph-container hero-slogan-p\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"paragraph-container hero-slogan-p\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0887\/2833\/8717\/files\/111111.png?v=1778930014\" alt=\"\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"paragraph-container hero-slogan-p\"\u003e\n\u003cstrong\u003ePRODUCT FEATURE\u003c\/strong\u003e \u003c\/div\u003e\n\u003cdiv class=\"paragraph-container hero-slogan-p\"\u003e\n\u003cp class=\"accordion-body-feature-description\"\u003eCastelli's Fast Feet project — for maximum aerodynamics\u003c\/p\u003e\n\u003cp class=\"accordion-body-feature-description\"\u003eFoot portion based on Castelli Rosso Corsa Sock for in-shoe comfort\u003c\/p\u003e\n\u003cp class=\"accordion-body-feature-description\"\u003ePolyurethane grip strip at top to keep sock in place\u003c\/p\u003e\n\u003cp class=\"accordion-body-feature-description\"\u003eLeg portion constructed with engineered grooved Lycra® to help detach airflow\u003c\/p\u003e\n\u003cp class=\"accordion-body-feature-description\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"CASTELLI","offers":[{"title":"White \/ L\/XL","offer_id":51295868420381,"sku":"CA-4526030-001-L\/XL","price":190.0,"currency_code":"MYR","in_stock":true},{"title":"White \/ 2XL","offer_id":51295868453149,"sku":"CA-4526030-001-2XL","price":190.0,"currency_code":"MYR","in_stock":true},{"title":"ROSA GIRO \/ L\/XL","offer_id":51295868485917,"sku":"CA-4526030-025-L\/XL","price":190.0,"currency_code":"MYR","in_stock":true},{"title":"ROSA GIRO \/ 2XL","offer_id":51295868518685,"sku":"CA-4526030-001-2XL","price":190.0,"currency_code":"MYR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/2833\/8717\/files\/01-4526030-001.jpg?v=1778931052","url":"https:\/\/turbomad.com\/products\/castelli-fast-feet-4-sock","provider":"Turbomad Cycle","version":"1.0","type":"link"}
