{"product_id":"fast-feet-4-sock-4526030","title":"FAST FEET 4 SOCK","description":"世の中には「エアロソックス」と呼ばれるものがたくさんあります。\nしかし Castelli Fast Feet 4 ソックスには、確かな開発とテストの裏付けがあります。\n\n多くのソックスは、テストといっても足を動かさない静止状態で行われているのが現実。でも実際のライドでは、足は常に動いています。\nそこで私たちは、脚の動きを再現する専用のテスト機器を開発し、さらに実際のライダーでも検証を重ねました。\n\nその結果、時速50kmで2ワットのセーブを実現。\n最新モデルではカフ（履き口）のフィット感も改良され、より快適に、さらに空力性能を高めています。","brand":"Castelli","offers":[{"title":"001 \/ s\/m","offer_id":58372620026240,"sku":"4526030_001_58_S-M","price":6600.0,"currency_code":"JPY","in_stock":true},{"title":"001 \/ l\/x","offer_id":58372620878208,"sku":"4526030_001_58_L-X","price":6600.0,"currency_code":"JPY","in_stock":true},{"title":"001 \/ xxl","offer_id":58372282614144,"sku":"4526030_001_58_XXL","price":6600.0,"currency_code":"JPY","in_stock":true},{"title":"010 \/ s\/m","offer_id":58372721410432,"sku":"4526030_010_58_S-M","price":6600.0,"currency_code":"JPY","in_stock":true},{"title":"010 \/ l\/x","offer_id":58372721246592,"sku":"4526030_010_58_L-X","price":6600.0,"currency_code":"JPY","in_stock":true},{"title":"010 \/ xxl","offer_id":58372719378816,"sku":"4526030_010_58_XXL","price":6600.0,"currency_code":"JPY","in_stock":true},{"title":"025 \/ s\/m","offer_id":58372717478272,"sku":"4526030_025_58_S-M","price":4290.0,"currency_code":"JPY","in_stock":false},{"title":"025 \/ l\/x","offer_id":58372720918912,"sku":"4526030_025_58_L-X","price":4290.0,"currency_code":"JPY","in_stock":true},{"title":"025 \/ xxl","offer_id":58372720230784,"sku":"4526030_025_58_XXL","price":4290.0,"currency_code":"JPY","in_stock":true},{"title":"458 \/ s\/m","offer_id":58372717969792,"sku":"4526030_458_58_S-M","price":4290.0,"currency_code":"JPY","in_stock":true},{"title":"458 \/ l\/x","offer_id":58372719968640,"sku":"4526030_458_58_L-X","price":4290.0,"currency_code":"JPY","in_stock":false},{"title":"458 \/ xxl","offer_id":58372718526848,"sku":"4526030_458_58_XXL","price":4290.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/3307\/0720\/files\/image_88af9d16-85fd-4d6f-8395-9b88c77609d9.jpg?v=1783082281","url":"https:\/\/www.castelli-cycling.com\/ja-jp\/products\/fast-feet-4-sock-4526030","provider":"Castelli Cycling","version":"1.0","type":"link"}
