In 1983, Nike released a running shoe that would quietly become the most successful in the company's history. It wasn't the flashiest, the most expensive, or the most technologically radical. It was designed to do one thing: give everyday runners premium cushioning at an honest price. They called it the Pegasus, after the winged horse of Greek mythology. Forty years and over forty iterations later, it's still flying.
The Birth of a Legend: 1983
The story begins in Nike's design lab in the early 1980s, during the height of the jogging boom. Mark Parker, then a young footwear designer who would later become Nike's CEO, set out to create a shoe that could bring Air cushioning to the masses. He collaborated with Bruce Kilgore, the designer concurrently working on the Air Force 1, and outsole specialist Bill Peterson.
The shoe was initially called the "Air Wedge Trainer" in internal catalogs. But Parker had another idea for the name. He dropped "Pegasus" into a suggestion bowl, and it was chosen. In Greek mythology, Pegasus is a winged divine horse, born from the blood of Medusa. The name captured something essential: the sensation of flying on Air.
Priced at just $50, the original Pegasus democratized Nike Air technology. Early advertisements proudly declared: "Never will so many own so much for so little." The shoe debuted as a prototype at the 1982 New York City Marathon, selling 8,000 pairs in its first month. By the end of 1983, nearly 300,000 pairs had sold.
Four Decades of Innovation
What makes the Pegasus remarkable isn't any single model. It's the relentless cycle of refinement, year after year, decade after decade. The shoe has survived cancellations, design controversies, and complete platform reinventions, always returning to its core mission: reliable, accessible performance.
- 1983 Pegasus 1Debuts the heel-only Air Wedge, EVA foam midsole, nylon/mesh upper, and waffle outsole. The prototype sells out at the NYC Marathon.
- 1987 Nike Air PegasusDoubled heel Air volume and refined EVA foam. Becomes Nike's top-selling running shoe by 1988.
- 1996 Visible Air ControversyNike adds a visible Air window to chase the Air Max aesthetic. Runners reject it, preferring function over fashion. Sales plummet.
- 2000 The ResurrectionNike cancels the Pegasus in 1997, replaces it with the "Arma" in 1998, then brings it back as part of the Bowerman Series. Designer Sean McDowell returns to the "no junk" philosophy, burying the Air unit back inside the heel.
- 2010 Pegasus 27 — Zoom AirIntroduces low-profile, high-pressure Zoom Air for a snappier, more responsive ride. A fundamental shift in underfoot feel.
- 2018 Pegasus 35 — Full-Length ZoomThe biggest technological leap in the franchise's history. A full-length articulated Zoom Air unit, contoured to the foot's natural curve. Sells 12 million pairs in its first year.
- 2020 Pegasus 37 — React FoamRetires legacy Cushlon foam in favor of Nike React, delivering greater energy return and durability. Forefoot-only Zoom Air, twice as thick for explosive toe-off.
The Pegasus 38: The Art of Refinement
Released on April 29, 2021, the Pegasus 38 is a "corrector" shoe. It keeps the wildly successful React foam midsole from the Pegasus 37 but completely overhauls the upper, which had been widely criticized for heel slippage, lace bite, and a narrow fit.
The result is a shoe that honors its lineage while fixing its predecessor's flaws. A wider toe box allows toes to splay naturally. A padded, gusseted tongue eliminates lace bite. A redesigned midfoot webbing system integrates with the laces to pull the foot securely into the heel cup. The forefoot Zoom Air unit is pressure-tuned by gender, with women's models at 15 PSI and men's at 20 PSI, tailoring stiffness to different gait dynamics.
It retains the classic waffle outsole with strategically placed flex grooves and a lateral crash rail, a direct lineage to the original 1983 design. The engineered mesh upper offers breathable, multi-layered comfort built for high mileage.

Why the Pegasus Endures
The Pegasus is Nike's all-time best-selling running shoe, and the reason is almost counterintuitive. Nike never designed it to be the absolute best at any single thing. Instead, the Pegasus was engineered to rank just behind the leader in every performance metric: light enough for tempo runs, cushioned enough for recovery days, durable enough for hundreds of miles. It's a jack-of-all-trades, and that versatility is its superpower.
"While the Air Jordan and Air Max lines captured pop-culture hype, the Pegasus remained the blue-collar champion of the Nike catalog, celebrated by running store employees as the most reliable shoe to recommend to anyone who walks through the door."
Nike has used the Pegasus to democratize premium technology, delivering innovations like React foam, Zoom Air, and Flywire to the masses at accessible price points. It's the gateway shoe for recreational runners and the daily training tool for elite athletes alike. Eliud Kipchoge, the only human to run a sub-two-hour marathon, logs his base-building miles in the Pegasus. Mo Farah helped design the 30th and 31st editions. Joan Benoit Samuelson, winner of the first women's Olympic marathon in 1984, has been a Pegasus ambassador for decades.
Even Nike co-founder Phil Knight wears black Pegasus sneakers to black-tie dinners and board meetings, a quiet endorsement that transcends marketing.
The Legacy Continues
Forty years after Mark Parker dropped a name into a suggestion bowl, the Pegasus has sold hundreds of millions of pairs across more than 40 iterations. It has been cancelled and resurrected, ridiculed and revered, and through it all, it has remained true to its original design philosophy: give people what they need and don't overbuild.
The Pegasus 38 sits comfortably in that lineage. It's not a revolution. It's a refinement, the kind that comes from four decades of listening to runners and making small, deliberate improvements. That's the Pegasus way, and it's why the winged horse is still flying.
