The womens Scott Supertrac Ultra RC essentially takes all the incredible grip of the Supertrac RC but with high cushioning, great for hard surfaces and higher mileage including ultra marathon distance (hence the name). Even the, still modest, 8mm drop has been thought out to help assist you when pushing your distances. You really need to experience the eRide technology that Scott use in their running shoes. It is similar to other \'rocker\' designs, in that it promotes your best form by encouraging you onto your forefoot and then a quick take off. The Scott Supertrac Ultra RC would be great for serious off-road runners that tackle higher mileage on hard packed trails here in the UK. Scott say: \"The latest addition to the SCOTT RC footwear collection. Designed for ultras, the Supertrac Ultra RC\'s traction has been adapted to provide grip and stability for when the body gets tired. The midsole offers a higher drop at 8mm which better fits slower paces. The Swiss made Schoeller Dynamic fabric is used for the first time in footwear to deliver an unprecedented level of comfort and durability, both essential in ultra running. If you\'re planning on running an ultra, that\'s the shoe you need.\" IDEAL FOR: Tricky Off-road, Harder Packed, Mud and Obstacle Courses UPPER: Mesh/KPU LOWER: AeroFoam+/Rubber HEEL: 29mm FOREFOOT: 21mm HEEL TO FOREFOOT DROP 8mm FEATURES Wet Traction Rubber Engineered EVA Self Cleaning Lug Positioning One-piece upper Toe guard protection Schoeller Dynamic Fabric APPROX.
