Keep them going further with the shoe technology that is refered to as ï¿½An Energy Drink For Your Feetï¿½! The Zig Dynamic is a great shoe for youth looking for versatility. Main FeaturesWeight: 9.4 ounces (youth size 5).SmoothFitï¿½ synthetic mesh upper.ZigTechï¿½ multi-surface outsole.Reflective accents, removeable insole.Additional InformationThe styling of the Zig Dynamic is truly unique and one that will turn a lot of heads on the playground or even for Olympic athletes.ï¿½I love the looks I get from people as I run in them,ï¿½ says Nick Willis, silver metal winner in the 1500-meter at the 2008 Olympics in Beijing. ï¿½People canï¿½t help but stare at my shoes.ï¿½Thanks to the mono-mesh SmoothFitï¿½ upper and removable foam sockliner, the Zig Dynamic has both looks that turn heads and a fit that feels great. The improved feel of the upper reduces chafing and keeps feet secure for hours of training, a.k.a. ï¿½playingï¿½.But the real show stopper is the zig-zag shaped midsole/outsole of ZigTechï¿½ technology. This unique design absorbs and redirects the impact of footstrike through the midsole to the forefoot, where it is then applied to propulsion on toe-off. The result is an energy-return system that taxes muscles less, allowing young people to run harder and have more fun in the shoe. The natural flex grooves the ZigTechï¿½ pattern creates give a smooth transition throughout the gait cycle and combine with multi-surface traction insets to create a shoe that will go anywhere the fun goes.
