{"product_id":"r1-womens","title":"R1 Women's","description":"\u003ch2\u003eUltra-Distance Shoes for Long Road Runs\u003c\/h2\u003e\n\u003cp\u003eThese road running shoes are designed for road runners who continue to run long distances, such as ultra-marathons over 100km and stage races. They prioritize maintaining a consistent rhythm for extended periods and reducing strain on the feet, rather than simply running fast.\u003c\/p\u003e\n\u003cp\u003eThe shoes weigh approximately 240g for a US men's size 9. They have a stack height of 35mm at the heel and 27mm at the forefoot, with an 8mm drop. While ensuring ample cushioning, they are also lightweight enough for ultra-distance use. These shoes are suitable for distances longer than a full marathon, long road runs, daily mileage training, and ultra-marathon training.\u003c\/p\u003e\n\u003cp\u003eUnlike racing shoes with carbon plates that prioritize strong propulsion, the R1 focuses on long-lasting comfort, fit adjustment, and sustained cushioning. In ultra-marathons, where pace varies and foot conditions change, the ability to continue running comfortably until the end is of great value.\u003c\/p\u003e\n\u003ch3\u003eTUNEDFIT Dual Lacing System for Feet that Change Over Long Distances\u003c\/h3\u003e\n\u003cp\u003eThe R1 features the TUNEDFIT Dual Lacing System. With a two-zone structure that allows for separate tightening of the forefoot and midfoot, the fit can be easily adjusted to suit the condition of your feet.\u003c\/p\u003e\n\u003cp\u003eIn ultra-marathons and long runs, feet can swell as the distance increases, causing discomfort from pressure around the instep. Conversely, downhill sections or fatigue can lead to slippage within the shoe. By being able to adjust specific areas rather than tightening the entire shoe at once, you can achieve a secure hold without over-tightening.\u003c\/p\u003e\n\u003ch3\u003eDual-Zone ZeroSag for Sustained Cushioning\u003c\/h3\u003e\n\u003cp\u003eThe midsole incorporates two ZeroSag units. The official page describes this as a structure designed to maintain cushioning and a springy feel until the end, even during ultra-long distances.\u003c\/p\u003e\n\u003cp\u003eFor long road runs, it's not just the initial softness that matters, but how much cushioning remains in the later stages. Even when legs are tired and form tends to break down, the stable cushioning of the shoes helps maintain rhythm.\u003c\/p\u003e\n\u003ch3\u003eLightCELL Midsole for Lightweight and Energy Return\u003c\/h3\u003e\n\u003cp\u003eThe R1's midsole features a LightCELL midsole. The official page describes it as a nitrogen-infused foam that combines lightness with energy return.\u003c\/p\u003e\n\u003cp\u003eOver distances of 100km or more, the weight of shoes accumulates as a small burden. However, prioritizing lightness alone can often lead to insufficient cushioning and stability. The R1 is characterized by a balance that provides the necessary cushioning for long road runs while keeping the weight down to 240g.\u003c\/p\u003e\n\u003ch3\u003eGOFLOW Midsole Geometry for Smooth Foot Transitions\u003c\/h3\u003e\n\u003cp\u003eThe GOFLOW Midsole Geometry is a biomechanically designed shape that guides smooth, flowing foot transitions.\u003c\/p\u003e\n\u003cp\u003eIn ultra-marathons, maintaining efficient movement for extended periods is more important than achieving bursts of speed. A smooth transition from landing to toe-off significantly aids in steadily covering long distances.\u003c\/p\u003e\n\u003ch3\u003e2-Layer Jacquard Mesh for Breathability and Durability\u003c\/h3\u003e\n\u003cp\u003eThe upper uses two types of jacquard mesh. It features a two-layer structure that balances durability and breathability, while also using 40% recycled polyester.\u003c\/p\u003e\n\u003cp\u003eOn long road runs, foot stuffiness, chafing, and heat buildup inside the shoes can lead to problems in the later stages. A breathable upper is an important factor in maintaining comfort during long runs. Additionally, for multi-day events like stage races, the durability of the upper provides peace of mind.\u003c\/p\u003e\n\u003ch3\u003eFor Ultra-Marathoners and Long-Distance Road Runners\u003c\/h3\u003e\n\u003cp\u003eThe R1 is a shoe suited for road ultra-marathons, long-distance runs, stage races, and runners who accumulate long runs. Rather than a stiff racing shoe designed for speed, it is a model that prioritizes comfort and stability for running long distances.\u003c\/p\u003e\n\u003cp\u003eThe lacing system, which accommodates foot swelling, the ZeroSag for sustained cushioning, the lightweight and responsive LightCELL midsole, and the GOFLOW geometry for smooth foot transitions all combine to make this a user-friendly shoe for runners who want to maintain a steady rhythm over long road distances.\u003c\/p\u003e\n\u003ch3\u003eAbout the Brand Mount to Coast\u003c\/h3\u003e\n\u003cp\u003eMount to Coast is a performance footwear brand with roots in long-distance running. They address the challenges encountered in ultra-running and long-distance events and develop shoes for continuous long-distance running.\u003c\/p\u003e\n\u003cp\u003eOver long distances, problems that are less apparent over shorter distances emerge, such as foot swelling, changes in fit, midsole deterioration, and outsole durability. Mount to Coast starts with these actual challenges faced by ultra-runners to develop shoes that emphasize fit adjustment, sustained cushioning, and long-lasting comfort.\u003c\/p\u003e\n\u003cp\u003eThe R1 embodies this philosophy as a road running shoe. It is positioned not merely as a light and fast shoe, but as a shoe for maintaining a steady pace over 100km or longer road distances, while minimizing foot stress.\u003c\/p\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100.087%; height: 235.126px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eCategory\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eRoad Running\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eRecommended Usage\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eUltra-marathons over 100km, Stage Races\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eTarget Pace\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003e4:00〜8:00 min\/km\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eUpper\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003e2 types of jacquard mesh (40% recycled polyester)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eWeight\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003e240g (US Men's 9 inches)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eStack Height\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eHeel 35mm \/ Forefoot 27mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eDrop\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003e8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eLacing System\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eTUNEDFIT Dual Lacing System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eMidsole Structure\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eDual-Zone ZeroSag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eMidsole\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eLightCELL Midsole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eGeometry\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eGOFLOW Midsole Geometry\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 23.0868%; height: 19.5938px;\"\u003eCertification\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eAPMA (American Podiatric Medical Association) Certified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Mount to Coast","offers":[{"title":"White \/ US 6.0 (23.0cm)","offer_id":45086422139080,"sku":null,"price":208.0,"currency_code":"USD","in_stock":false},{"title":"White \/ US 6.5 (23.5cm)","offer_id":45086422171848,"sku":"810160780021","price":208.0,"currency_code":"USD","in_stock":true},{"title":"White \/ US 7.0 (24.0cm)","offer_id":45086422204616,"sku":"810160780038","price":208.0,"currency_code":"USD","in_stock":true},{"title":"White \/ US 7.5 (24.5cm)","offer_id":45086422237384,"sku":"810160780045","price":208.0,"currency_code":"USD","in_stock":true},{"title":"White \/ US 8.0 (25.0cm)","offer_id":45086422270152,"sku":"810160780052","price":208.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0554\/0308\/6024\/files\/r1_white_sub1.jpg?v=1779243408","url":"https:\/\/rockstepper-jp.com\/en-en\/products\/r1-womens","provider":"ROCK STEPPERS","version":"1.0","type":"link"}
