{"product_id":"chaussettes-fast-feet-4","title":"FAST FEET SOCKS 4","description":"\u003cp\u003eFast Feet 4 Socks: Castelli Fast Feet socks are based on a design and testing process that meets aerodynamic requirements. Many so-called \"aerodynamic\" socks are on the market, but Castelli Fast Feet 4 socks are based on a design and testing process that actually supports this claim. The few socks that have been tested have likely undergone static, rather than dynamic, testing, as the process is simpler. However, a foot is always in motion, which is why we created a template that replicates the movement of the lower leg. Furthermore, we tested this model on real cyclists to verify the results. These socks can help you gain 2 watts of power at 50 km\/h. The latest version features an upgraded top band for increased comfort and improved aerodynamics. Castelli's Fast Feet project: for maximum aerodynamics\n \u003cbr\u003eThe foot section is based on the Castelli Rosso Corsa Sock, to guarantee your comfort in the shoe.\n\u003cbr\u003e Polyurethane band at the top to hold the sock in place\n\u003cbr\u003e Leg section made of grooved Lycra® specially designed to reduce air resistance. For road races or when you cannot wear Fast Feet TT Shoecover overshoes, these socks allow you to save energy.\u003c\/p\u003e","brand":"CASTELLI","offers":[{"title":"WHITE \/ L\/X","offer_id":53803044372820,"sku":"4526030-001-L\/X","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"WHITE \/ S\/M","offer_id":53803044405588,"sku":"4526030-001-S\/M","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"WHITE \/ XXL","offer_id":53803044438356,"sku":"4526030-001-XXL","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"BLACK \/ L\/X","offer_id":53803044471124,"sku":"4526030-010-L\/X","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"BLACK \/ S\/M","offer_id":53803044503892,"sku":"4526030-010-S\/M","price":32.0,"currency_code":"EUR","in_stock":false},{"title":"BLACK \/ XXL","offer_id":53803044536660,"sku":"4526030-010-XXL","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"ROSA GIRO \/ L\/X","offer_id":53803044569428,"sku":"4526030-025-L\/X","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"ROSA GIRO \/ S\/M","offer_id":53803044602196,"sku":"4526030-025-S\/M","price":32.0,"currency_code":"EUR","in_stock":true},{"title":"ROSA GIRO \/ XXL","offer_id":53803044634964,"sku":"4526030-025-XXL","price":32.0,"currency_code":"EUR","in_stock":false},{"title":"AZZURRO ITALIA \/ L\/X","offer_id":53803044667732,"sku":"4526030-458-L\/X","price":32.0,"currency_code":"EUR","in_stock":false},{"title":"AZZURRO ITALIA \/ S\/M","offer_id":53803044700500,"sku":"4526030-458-S\/M","price":32.0,"currency_code":"EUR","in_stock":false},{"title":"AZZURRO ITALIA \/ XXL","offer_id":53803044733268,"sku":"4526030-458-XXL","price":32.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0765\/4755\/5668\/files\/01_4526030_001.png?v=1771962701","url":"https:\/\/triathlonstore.eu\/products\/chaussettes-fast-feet-4","provider":"Triathlon Store","version":"1.0","type":"link"}
