Under Armour TriBase Reign 5 W

The i-Run team says

Technologies

• Micro G

  Ultra-lightweight and extremely dynamic foam (energy return) with good cushioning quality

• UA TriBase

  Maximize ground contact with three points of contact to ensure exceptional stability and a natural foot roll

• UA Warp

  UA Warp is a revolutionary upper that perfectly conforms to the human form to boost performance. It features support bands that act like seat belts on the foot, placed precisely where our biomechanists have found them most useful for a runner. The bands tighten when you need them and loosen when you don't, thereby eliminating common pressure points associated with continuous materials.
