Based on a review by Believe in the Run (accessed 2026-03-17).
Based on this review alone: buy it if you care about nails the fit with a comfortable, breathable double mesh upper — just accept performance is a "one-trick pony," lacking excitement compared to some other shoes.
Thomas, initially unexcited, was "immediately surprised" that he actually liked the Pegasus 42, calling it a "really good update." He gave it an A for design and value, but a C for performance due to its firmer ride. He concludes with an overall B grade and a "green light," recommending it as an above-average daily trainer.
Thomas from Believe in the Run reviews the Nike Pegasus 42, focusing on its design, fit, midsole technology including ReactX foam and an Air Zoom unit, outsole, weight, and price. He provides detailed feedback on his running experience and offers overall ratings for design, value, and performance.
The Nike Pegasus 42 is a surprisingly good update to the storied daily trainer, offering a comfortable and reliable ride that exceeds expectations from previous iterations. The fit of the double mesh upper is perfectly dialed in, providing comfort and breathability, while the full-length curved Air Zoom unit delivers noticeable energy return, making the 10mm drop feel more cushioned. However, its performance as a "one-trick pony" means it lacks the exciting, plush feel found in some competitors, leaning towards a firmer ride. If you prioritize a consistent, durable, and comfortable shoe for daily training miles and gym activities, this is an excellent choice. If you seek a shoe with a more exciting or softer, bouncier ride for specialized performance, you might want to explore other options.

Nike claims to have opened up the toe box for more accommodation. The reviewer observes some puckering, suggesting there might be additional room, although he didn't personally need it.

The shoe features resilient ReactX foam, which is described as more resilient and fun than the original React foam, but otherwise familiar.

The full-length curved Air Zoom unit was very noticeable, providing energy return and bounce during the running stride and foam compression.

Despite a 10mm drop (37/27mm stack height), the Air Zoom unit makes the 27mm forefoot feel more cushioned, providing a bouncy sensation off the toes.

The combination of ReactX and the Zoom Air unit results in a really nice, comfortable running shoe in terms of cushioning.

The shoe features a waffle outsole, which the reviewer notes is pretty much what users are accustomed to from Nike.

A size 10 of the shoe weighs 10.6 oz (300 g), which the reviewer considers "not that bad" and "right there in the middle" for its category.

At $145, the Pegasus 42 offers good value, fitting into a competitive price point for entry-level or slightly above premium performance shoes, and provides longevity.

The reviewer gave performance a C, describing the shoe as a "one-trick pony" and feeling a "little bit on the firmer side" compared to softer options like the New Balance Elipus.
Initially skeptical, the reviewer was "immediately surprised" by how much he liked the Pegasus 42, calling it a "really good update." He found it to be above average for daily runs, giving it an overall grade of B and a "green light."
The engineered mesh double upper provides a great, dialed-in fit, with a comfortable tongue and well-designed heel collar. The reviewer experienced no complaints and found it to be true to size, fitting well in his usual size 10.5.
The midsole combines resilient ReactX foam with a noticeable full-length curved Air Zoom unit. This combination provides a comfortable, bouncy, and energetic sensation, making the cushioning feel more generous than the stack height might suggest, especially with a good bounce off the toes.
The reviewer measured the Nike Pegasus 42 in a men's size 10 to weigh 10.6 ounces, or 300 grams. He considers this weight to be "not that bad" and right in the middle for a daily trainer of its type.
Priced at $145, the reviewer gives the Pegasus 42 an 'A' for value. He notes this price point is common for entry-level or slightly above premium performance shoes. Its robust ReactX foam, ample outsole rubber, and sturdy upper contribute to its longevity, making it a great durable option for daily runners.
Unlike previous Pegasus models that the reviewer would only use for 4-5 mile runs, he comfortably completed several 8-mile runs in the Pegasus 42. He states it felt great and is suitable for daily training miles, including longer distances.
The reviewer gives the Pegasus 42 a C for performance, describing it as a "one-trick pony." While it provides a good, comfortable ride for daily training, it is a "little bit on the firmer side" compared to softer, more exciting shoes. Its performance is reliable but may not offer the plushness or energetic feel sought by all runners.
