{"product_id":"cs2603001011","title":"Castelli Fast Feet 4 Socks Black \/ 2XL","description":"\u003cp\u003eThere are lots of so-called aero socks out there. 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 they created a jig that replicates the movement of the lower leg. And they 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\/p\u003e","brand":"saddleback","offers":[{"title":"2XL \/ Black","offer_id":55617804075393,"sku":"CS2603001011","price":40.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3982\/5547\/files\/cs2603001009_444bc046-4ac5-423c-af48-261dc4eac0f7.jpg?v=1777739779","url":"https:\/\/scuffwheels.com\/ru\/products\/cs2603001011","provider":"Scuff Wheels","version":"1.0","type":"link"}
