When the going gets tough... then our limited edition Challenge Roth Gravity 11 is just the shoe to keep you going. It crowns the official partnership between DATEV Challenge Roth powered by hep 2022 and Newton Running. There is probably no shoe with more TRI spirit, because we designed it with a lot of heart and love for one of the greatest triathlon events in the world. The latest model update of our lightweight performance neutral shoe the Gravity 11, has added a lot of power to the sole with our new Newtonuim X cushioning. The power formula of this cushioning is as simple as it is effective: more in, more out! This means the Hytrel® foam that Newtonium X is made of absorbs more of your impact energy and then releases more back to you. Since almost no energy is lost, the Gravity 11 gets you across the asphalt quickly, energy-efficiently and comfortably. If you want to be faster than yesterday, the new Gravity 11 is your shoe for this season! It's all in the new Newton Gravity 11: P.O.P 1 (Point of Power): The visible Action/Reaction™ technology of the shoe is the P.O.P 1 cushioning unit. The lugs in the front midfoot area make the force that acts on this area during the impact phase available again as energy for your push-off phase.New Newtonium X cushioning: The cushioning developed for the new 2022 Newton models corresponds perfectly with the P.O.P.1 system. The full -length, layer made of Hytrel® foam which returns energy quickly, allows you an extremely reactive, cushioned run without unnecessary energy loss.3.0 mm drop: The slight difference in stack height between forefoot and rearfoot allows you to run more naturally which helps to improve your running efficiency.244 grams weight (women: 205 grams): The light weight of the shoe makes your running style more dynamic and energy efficient.Tactical Flex Grooves: The flex grooves are tactically placed to mirror your foot motion and thus a dynamic running form. The upper material: 3-D Engineered Air Mesh: The anatomically shaped, soft air mesh in the upper adapts perfectly to the shape of your foot and ensures a good foot climate.Seamless upper: There are no irritating pressure points or friction caused by seams with this upper material.Flexible lacing system: The lacing lies over the entire instep and can be easily adjusted individually. This gives you support and security and avoids pressure points.Anti-Friction Lining: The inner lining is soft to prevent friction and blisters.   Recycled and biodegradable features: Laces: 100% recycled polyester.Mesh upper: 100% recycled polyesterMidsole: EVA with EcoPure®Lug membrane: Hytrel® with EcoPure®Outsole: Rubber with EcoPure® The Newton Gravity 11 is the perfect shoe for you…. …if you prefer an active and natural running style and like to run faster sessions on asphalt and paved surfaces.
