NRG55 Sole material vs regular eva vs concrete.


Most athletic work shoes are made with a simple EVA compound that is hard and uncomfortable.  The NRG55's extreme cushioning absorbs your heal strike and returns a responsive performance you have never felt before. 

NRG55 VS the competition

Built on 2 densities of the NRG55 advanced sole blend, the NRG55 sole returns 55% of the energy it receives and approximately 50% more than the average performance of safety shoes within the same class. More energy return means less wasted energy and more energy left in your tank.
