The Nike Pegasus 41 road running shoes feature responsive cushioning for everyday road running. Dual Air Zoom units and a ReactX foam midsole provide lighter-weight energy return. The upgraded engineered mesh upper decreases weight and increases breathability. It features a lace up fastening, signature waffle-inspired rubber outsole for traction and flexibility, and a plush collar tongue and sockliner for a secure and comfortable fit. The ReactX foam midsole is more responsive than previous React technology and is engineered to reduce its carbon footprint by at least 43% in a pair of midsoles due to reduced manufacturing process energy compared to prior React foam. The carbon footprint of ReactX is based on cradle-to-gate assessment. These sneakers have a weight of approximately 251 g/8.8 oz (US 8) and a heel-to-toe drop of 10 mm.
