Product DetailsThe On Running Cloudrunner makes concrete easy. An enforced CloudTec system with 15 high-profile Clouds absorbs heavy impact and provides the best stability and underfoot protection.Unleash the natural energy of your feet and promote an efficient running gait. Win the battle beneath your feet and transform impact into a light, natural run.The Cloudrunner is designed for high-impact runs, long training sessions and endurance runs. Run on clouds: build your endurance, prevent injury and reduce recovery times.The active sole balances every step and trains the running muscles, too. The Cloudrunner intelligently combines what traditional running shoes have failed to unite: a light impact and a quick push-off for both training and competition use.Weight: 315 g | 11.1 oz. (men's US 8.5)Heel-toe offset: 7 mmRunner profileAll types of runner, including high-impact and endurance runners.Build endurance, train on and off the road.Target speed:5-6 min/km8-9.5 min/mileCloudTec explained1. The On is the first running shoe with 3D cushioning, absorbing not only the vertical impact, but also the horizontal shock from the forward movement – the so called shearing forces which cause muscle cell destruction and pain in ligaments and joints.2. The On makes you run light and fast, and pain free. When running, you want to land soft and push off hard. The CloudTec elements allow your foot to travel softly into your landing. Once locked, the Clouds are completely firm for a powerful push-off. This is possible to the fact that the On uses travel (distance) to slow down impact forces rather than just compressing rubber or air like other cushioning systems.3. The On is the new approach to motion control: By activating your muscles, the On enables you to stabilize and control your foot strike naturally – without artificial support.4. The On fosters an efficient running style, allowing the runner to land more forward on his or her foot as well as to adopt a centered and energized running position. The Integrated Transition Bridge flexes over the whole length of the shoe, making it the best rolling shoe on the market. Combined with your Cloud-activated muscles, this results in a shorter ground contact time.5. On’s intelligent cushioning allows for a minimalistic, lightweight construction in line with the latest research on the natural movement of the foot, i.e. a low heel-to-toe ratio, being close to the ground, and very good torsional flex in the mid-foot.6.The NEW 4 layers speedboard (all the 2014 models)- Layer 1 - flex power - Hit the ground in a nice and rolling movement. The lengthwise rails translate landing impact into forward propulsion.- Layer 2 - energy distribution - The diagonal grid ensures even energy distribution, interacting with the CloudTec sole.- Layer 3 - torsion guidance - The high-density grid guides your foot through a natural torsion phase - not limiting your freedom of movement.- Layer 4 - spiral dynamics - The transversal grid supports the natural gait of your foot in a spiral motion. Land on the outer side of your foot and push-off on your big toe.
