The Pegasus 41 road running athletic sneakers by Nike feature lighter-weight energy return with dual Air Zoom units and a ReactX foam midsole. The upgraded breathable engineered mesh upper decreases weight and increases breathability. The signature waffle-inspired rubber outsole provides traction and flexibility. The plush collar tongue and sockliner ensure 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%. The sneakers have lace-up fastening. They weigh approximately 297 g/10.4 oz (Men's US 10) and have a heel-to-toe drop of 10 mm.
