Nike Pegasus 42 Specs and Details

As Nike’s longest tenured and best-selling running shoe franchise, first introduced in 1982, Pegasus reflects a legacy of responsive cushioning for all-day energy return

“We’ve taken what runners have always loved about the Pegasus franchise and turned it into the best version yet with the Pegasus 42,” says Elliott Heath, senior footwear expert, Nike Running. 

With 15 percent greater energy return than its predecessor, the Pegasus 42 is powered by a curved, full-length Air Zoom unit, making it exciting to lace up for jogs, community runs, training sessions and more. The fine-tuned Air experience provides a propulsive feel reminiscent of Nike’s legendary road racing footwear but engineered for everyday runs. More than ever, each Air Zoom unit is designed for maximum responsiveness — creating a bouncy, powerful sensation never before felt in a Pegasus model.

A modified last offers a more accommodating fit and improved forefoot cushioning, especially under the toes, where an innovative spring structure accommodates an additional 3mm of cushioning without adding to the stack height in the rest of the shoe.

A plush ReactX foam midsole maintains continuity from the Pegasus 41, and a modernized waffle outsole enables smooth transitions while delivering confident traction on a variety of surfaces.

All the while, a midfoot support system and fully molded sock liner promote a comfortable, secure fit, and a new lightweight, breathable upper seamlessly conforms to the foot.
