The Pegasus 41 road running sneakers feature dual Air Zoom units and a ReactX foam midsole. The engineered mesh on the upper decreases weight and increases breathability. The ReactX foam midsole surrounds forefoot and heel Air Zoom units. It's 13% more responsive than previous React technology. The waffle-inspired rubber outsole provides traction and flexibility. The collar, tongue and sockliner provide a secure and comfortable fit. These Nike sneakers have reflective details and a lace-up closure. They weigh approximately 251g/8.9oz and have a heel-to-toe drop of 10mm.
