Reebok

It's like an energy drink for your feet. As Reebok's most technically advanced training shoe to date, ZigTech allows key leg muscles to do less, so you can do more. Its patented sole technology conserves and returns energy for a soft and springy ride. ZigTech, one-of-a-kind zig-zag-shaped sole, absorbs the impact of heel strike and propels you forward, while reducing wear and tear up to 20% in key leg muscles. Has a synthetic/mesh upper ensures comfort, fit and durability, DMX Shear cushioning panels for added comfort and reduced heel stress; forefoot flex grooves for added flexibility, and a PU sockliner for added cushioning and support.
