{"product_id":"r1-mens","title":"R1 Men's","description":"\u003ch2\u003eUltra-Distance Shoes for Sustained Long Road Runs\u003c\/h2\u003e\n\u003cp\u003eThese road running shoes are designed for road runners tackling long distances, such as ultramarathons over 100km or multi-stage races. They prioritize maintaining a consistent rhythm and minimizing strain on the feet over extended periods, rather than just maximizing speed.\u003c\/p\u003e\n\u003cp\u003eWeighing approximately 240g for a US men's size 9, with a stack height of 35mm at the heel and 27mm at the forefoot, and an 8mm drop, these shoes offer ample cushioning while remaining lightweight for ultra-distance use. They are well-suited for distances even longer than a full marathon, extended road runs, daily mileage runs, and ultramarathon training.\u003c\/p\u003e\n\u003cp\u003eUnlike racing shoes that utilize carbon plates for strong propulsion, the R1 emphasizes long-lasting comfort, adjustable fit, and sustained cushioning. In ultramarathons, where pace fluctuates and foot conditions change, the ability to continue running comfortably to the end is of great value.\u003c\/p\u003e\n\u003ch3\u003eTUNEDFIT Dual Lacing System for Adapting to Foot Changes Over Long Distances\u003c\/h3\u003e\n\u003cp\u003eThe R1 features the TUNEDFIT Dual Lacing System. Its two-zone structure allows separate tightening of the forefoot and midfoot, making it easy to adjust the fit according to your foot condition.\u003c\/p\u003e\n\u003cp\u003eDuring ultramarathons or long runs, feet can swell, the instep might feel pressure, or conversely, downhill sections or fatigue can lead to slippage within the shoe. By being able to adjust specific areas separately 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 product page describes this structure as designed to maintain cushioning and a bouncy feel throughout even ultra-long distances, preventing the cushioning from breaking down.\u003c\/p\u003e\n\u003cp\u003eFor long road runs, it's not just about the initial softness but how much cushioning remains in the later stages. Even when legs are fatigued and form tends to break down, stable cushioning from the shoe helps maintain rhythm.\u003c\/p\u003e\n\u003ch3\u003eLightCELL Midsole for Lightweight Performance and Energy Return\u003c\/h3\u003e\n\u003cp\u003eThe R1's midsole features LightCELL Midsole technology. The official product page describes it as nitrogen-infused foam that balances lightweight properties with energy return.\u003c\/p\u003e\n\u003cp\u003eOver distances exceeding 100km, the weight of the shoe accumulates as a small but significant burden. However, prioritizing lightness alone can often lead to insufficient cushioning and stability. The R1 strikes a balance, offering the necessary amount of cushioning for long road runs while maintaining a weight of 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 the foot through fluid and smooth transitions.\u003c\/p\u003e\n\u003cp\u003eIn ultramarathons, maintaining efficient movement over a long period is more crucial than achieving momentary bursts of speed. A smooth flow from landing to toe-off significantly aids in consistently covering long distances.\u003c\/p\u003e\n\u003ch3\u003eTwo-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 incorporates 40% recycled polyester while also prioritizing durability and breathability.\u003c\/p\u003e\n\u003cp\u003eOn long road runs, foot perspiration, chafing, and heat buildup within the shoe can lead to issues in the later stages. A breathable upper is a crucial factor in maintaining comfort during extended running. Furthermore, in situations like stage races where you run daily, the durability of the upper provides peace of mind.\u003c\/p\u003e\n\u003ch3\u003eFor Runners Tackling Ultramarathons and Long Road Runs\u003c\/h3\u003e\n\u003cp\u003eThe R1 is designed for runners tackling road ultramarathons, extended mileage runs, stage races, and frequent long runs. It's a model that prioritizes comfort and stability for sustained long-distance running, rather than a rigid racing shoe focused on speed.\u003c\/p\u003e\n\u003cp\u003eThe lacing system adapts to foot swelling, the ZeroSag provides sustained cushioning, the LightCELL midsole offers lightweight responsiveness, and the GOFLOW geometry supports smooth foot transitions. These elements combine to make it a user-friendly shoe for runners who want to maintain a consistent rhythm over long road distances.\u003c\/p\u003e\n\u003ch3\u003eAbout the Mount to Coast Brand\u003c\/h3\u003e\n\u003cp\u003eMount to Coast is a performance footwear brand rooted in long-distance running. They address the challenges encountered in ultra-running and long-distance environments, developing shoes designed for sustained long runs.\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 breakdown, and outsole durability. Mount to Coast starts with these real challenges faced by ultra-runners to develop shoes that emphasize adjustable fit, sustained cushioning, and long-lasting comfort.\u003c\/p\u003e\n\u003cp\u003eThe R1 is a road running shoe that embodies this philosophy. It's positioned as a shoe not merely for light and fast running, but for sustaining runs over 100km or extended 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 Use\u003c\/th\u003e\n\u003ctd style=\"width: 74.0536%; height: 19.5938px;\"\u003eUltramarathons 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-layer 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 size 9)\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 7.0","offer_id":45086420959432,"sku":null,"price":27500.0,"currency_code":"JPY","in_stock":false},{"title":"White \/ US 7.5","offer_id":45086420992200,"sku":"810160781387","price":27500.0,"currency_code":"JPY","in_stock":true},{"title":"White \/ US 8.0","offer_id":45086421024968,"sku":"810160780342","price":27500.0,"currency_code":"JPY","in_stock":true},{"title":"White \/ US 8.5","offer_id":45086421057736,"sku":null,"price":27500.0,"currency_code":"JPY","in_stock":false},{"title":"White \/ US 9.0","offer_id":45086421090504,"sku":"810160780366","price":27500.0,"currency_code":"JPY","in_stock":true},{"title":"White \/ US 9.5","offer_id":45086421123272,"sku":null,"price":27500.0,"currency_code":"JPY","in_stock":false},{"title":"White \/ US 10.0","offer_id":45086421156040,"sku":"810160780380","price":27500.0,"currency_code":"JPY","in_stock":true},{"title":"White \/ US 10.5","offer_id":45086421188808,"sku":"810160780397","price":27500.0,"currency_code":"JPY","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\/products\/r1-mens","provider":"ROCK STEPPERS","version":"1.0","type":"link"}
