The Ultra 50 Running Shoe was developed especially for long runs on challenging alpine trails where safety and protection are demanded. This trail running shoe features excellent cushioning and a comfortable fit for comfort over distances of 40k or more. With a drop of 8 mm, the Alpine Rocker outsole design with rounded edges, plus a high level of cushioning allows the Ultra 50 to make for a dynamic run even on technical terrain. The 3D Mesh Construction and a seamless tongue ensure this shoe never pinches, effectively preventing pressure points while also lending stability for your feet. This shoe is also designed for ultra distances with its maximum volume. The Ultra 50’s Pomoca outsole stands out with its open, aggressive tread. This tread offers optimum grip and responsiveness both on dry surfaces as well as in adverse conditions. Reinforcing Ballistic Bumpers at the toe box and TPU overlays at sensitive areas protect feet from the effect of impacts on rocky terrain. With the traditional lacing system, you can customize a precise fit to your foot’s anatomy. The Invisible Lacing System’s extra fabric layer keeps laces stowed securely on runs and keeps dirt and stones from getting into your shoes. The time-tested Dynafit Heel Preloader lends extra support at the heel.
