The ULTRA TT 4.0 delivers a smooth balanced performance for your everyday training or racing, weighing in at 7.7oz.

Features of the Zoot Ultra TT 4.0 include:

• Fabric: BareFit - Sockless Wear=No Stink. Tri-Dry technology because water in shoes is weight on your feet. Patented Quick-Lace System with a one hand lock down. CarbonSpan+ because balanced support and powerful toe-off count. Asymmetrical design matches your foot.

• Tri-Dry

  Water in your shoes is weight on your feet. So, we developed TriDry technology to limit water retention and keep your shoes feeling light. After all, you didn't do all that training to have wet and heavy shoes on race day.

• CarbonSpan+

  CarbonSpan+ is lighter, stronger, and tuned to running. It's everything that plastic isn't. You will notice CarbonSpan+ provides a smooth powerful toe off.
