The Nike Air Zoom Pegasus 37 has undergone an impressive update that enhances its already well-loved design, making it an even more responsive and cushioned option for all types of runners. With a new React foam midsole and a larger forefoot air bag, this latest version strikes the perfect balance between comfort, responsiveness, and versatility.
Enhanced Cushioning and Energy Return
The Pegasus 37 is now equipped with a springier, more responsive React foam midsole, replacing the previous Cushlon ST foam. This change adds 2mm to the overall stack height, providing a slightly more cushioned feel. Combined with a larger air unit in the forefoot, this results in a snappy, energetic ride that keeps you moving without feeling sluggish or heavy. The air unit is now twice as large as in previous versions, offering an extra boost during each stride. Testers loved how the foam and air bag worked together to provide a comfortable yet responsive feel, especially for longer runs. “The cushioning is soft and smooth, but it doesn’t feel slow,” said one tester. “It’s the kind of ride that makes you want to keep going.”
Comfortable Upper with a Secure Fit
The upper of the Pegasus 37 has been updated to feature a thinner, form-fitting textile mesh that improves breathability while still offering a snug fit. It feels similar to the Vaporfly’s upper but is designed to accommodate a variety of foot shapes. The forefoot provides enough space without being too roomy, and a midfoot band replaces the previous Flywire cables to provide enhanced stability. This new system reduces pressure points and evenly distributes the tension from the laces, creating a more comfortable fit overall. Some testers found the heel cup slightly less secure than expected, but most appreciated the extra padding behind the Achilles for added comfort. The upper also ventilates well, although it tends to retain moisture slightly longer than other mesh constructions.
A Smooth, Snappy Ride
One of the standout features of the Pegasus 37 is how well it balances cushioning with responsiveness. The shoe’s midsole offers a plush feel, yet it never feels overly soft or sluggish. Whether you’re doing speed work or long runs, the foam provides just the right amount of bounce, helping you maintain energy without sacrificing comfort. Testers also noted that the shoe felt stable and supportive, with a great grip on both wet and dry surfaces. The rubber outsole, with long strips on the lateral side and rectangular lugs on the medial side, provides excellent traction and durability.
Durability and Grip
Unlike many brands that have reduced outsole rubber to save weight, Nike has kept plenty of rubber on the Pegasus 37 to improve grip and durability. The outsole features strategically placed rubber that provides extra cushioning and helps make the shoe feel more secure, even on tricky terrain like gravel. Whether you’re running on smooth pavement or more uneven surfaces, the traction on this shoe won’t let you down.
Tester Feedback
John K., a tester since 2020, noted that the Pegasus 37 felt durable and cushioned, offering a responsive ride that worked well for both longer runs and speed sessions. “The shoe has almost a racing fit, but it still feels comfortable for everyday use,” he said. Meanwhile, our deputy digital editor, Jane McGuire, has found the Pegasus 37 to be her go-to shoe for long-distance runs, especially half marathons and marathons. “It’s lightweight and responsive, with that extra push from the air zoom bag in the forefoot,” she explained. However, she also noted that faster runners may find the shoe a bit bulky for speed work or race day.
Final Thoughts
The Nike Air Zoom Pegasus 37 is a great all-purpose trainer for a wide range of runners. With its refined cushioning, secure fit, and responsive ride, it offers a fantastic combination of comfort and performance for both daily training and longer runs. Whether you’re training for a marathon or simply looking for a reliable, versatile shoe, the Pegasus 37 is a solid choice.
