But the Castelli Fast Feet 4 sock has the development and test results to prove that it lives up to its name. The few socks that have been tested were likely evaluated using a static test while at rest, because that’s easier. But since a foot is constantly in motion, we developed a device that simulates the movement of the lower leg. And we conducted tests with real cyclists to validate the results. This sock can save 2 watts at 50 km\/h. The latest version features an updated cuff fit for greater comfort and aerodynamics.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eFEATURES\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCastelli’s Fast Feet project – for maximum aerodynamics\u003c\/li\u003e\n\u003cli\u003eFoot area based on the Castelli Rosso Corsa socks for comfort inside the shoe\u003c\/li\u003e\n\u003cli\u003ePolyurethane grip strips at the top to prevent the sock from slipping\u003c\/li\u003e\n\u003cli\u003eLeg section made of specially developed, grooved Lycra® to optimise airflow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name\u003c\/strong\u003e: Castelli Fast Feet 4 Socks\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Castelli\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Main fabric: 85% polyester, 15% elastane\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnkle\u003c\/strong\u003e: 82% polyester, 18% elastane\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression\u003c\/strong\u003e: no\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivity\u003c\/strong\u003e: Cycling\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGender\u003c\/strong\u003e: men\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsage bikesport\u003c\/strong\u003e: Road Bike\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTextile fabric\u003c\/strong\u003e: Synthetics\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeason\u003c\/strong\u003e: All Season\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocks length\u003c\/strong\u003e: medium\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocks version\u003c\/strong\u003e: no padding\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel year\u003c\/strong\u003e: 2026\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollection\u003c\/strong\u003e: Spring\/Summer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 50g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Castelli","offers":[{"title":"White \/ S\/M","offer_id":43230861918269,"sku":"8056006588297","price":179.0,"currency_code":"AED","in_stock":false},{"title":"White \/ L\/XL","offer_id":43230861983805,"sku":"8056006588303","price":179.0,"currency_code":"AED","in_stock":true},{"title":"White \/ XXL","offer_id":43230861951037,"sku":"8056006588310","price":179.0,"currency_code":"AED","in_stock":true},{"title":"Black \/ S\/M","offer_id":43230861819965,"sku":"8056006588327","price":179.0,"currency_code":"AED","in_stock":false},{"title":"Black \/ L\/XL","offer_id":43230861885501,"sku":"8056006577857","price":179.0,"currency_code":"AED","in_stock":true},{"title":"Black \/ XXL","offer_id":43230861852733,"sku":"8056006588334","price":179.0,"currency_code":"AED","in_stock":true},{"title":"Rosa Giro \/ S\/M","offer_id":43230862016573,"sku":"8056006588341","price":179.0,"currency_code":"AED","in_stock":true},{"title":"Rosa Giro \/ L\/XL","offer_id":43230862082109,"sku":"8056006588358","price":179.0,"currency_code":"AED","in_stock":true},{"title":"Rosa Giro \/ XXL","offer_id":43230862049341,"sku":"8056006588365","price":179.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/5643\/0397\/files\/4bd2222a-c2fc-4d82-b606-cd76590eb38f.jpg?v=1779715096","url":"https:\/\/wolfis.ae\/products\/castelli-fast-feet-4-socks","provider":"Wolfi's","version":"1.0","type":"link"}
