The personal relationship you have with the Peg is unlike anything else. Faithful. Reliable. The pair that’s always there, pushing the running world forward, while still putting your wants and needs first. With an always speedy Zoom Air engine on top of softer, more responsive ReactX foam the Pegasus 41 is quietly unlike any other Peg we have ever made before. A springy ride for any run, better for all runners on this planet, and all planets where we run.

Hello, ReactX
Nike ReactX is a lightweight, durable foam that delivers a smooth, responsive ride—with much less impact. Providing 13% more energy return and 43% less carbon impact than regular React foam—ReactX makes this Pegasus unlike any before with less impact from heel to toe to earth.
Take Off, Zoom
We paired Nike ReactX technology with 2 Zoom Air units (1 in the forefoot and the heel) to give you a bouncy, springy sensation and an energized feel at toe-off.
Broader and Better
We broadened the forefoot and heel width compared to the Peg 40. The extra room provides a stable, springy Zoom Air engine for that extra horsepower when you need it.
Light and Breathable
The upper is made of an engineered mesh that’s even lighter and more breathable than the Peg 40 to create an inviting feel and fit. The inner confines of the shoe are comfortable, breathable and forgiving in the toes, arch and heel, where your feet are most sensitive.
Hugs The Foot
Built with the same internal materials and padding as its predecessor, the Pegasus 41 will hug your foot with an implemented midfoot band for a more secure but forgiving sensation. The midfoot strap for a more molded fit to the foot, shaped for all sized arches.
