Based on this review alone: skip it — reactx midsole is overly firm and lifeless for running, lacking response and bounce, unless very dependable and reliable, offering predictable performance is your only priority.
The reviewer concludes that the Nike Pegasus 42, while dependable, comfortable, durable, and stable, has largely become a 'lifestyle shoe' rather than a dedicated running shoe due to its overly firm, lifeless, and heavy ride. He suggests that for serious runners seeking an inspiring ride, other options, particularly Nike's Vomero 18, are far superior, and that the Pegasus 42 will likely end up in outlet stores.
This review provides an in-depth look at the Nike Pegasus 42 running shoe, detailing its updates from the previous version, its intended purpose, and various specifications. The reviewer also compares the Pegasus 42 to several popular competitor shoes, including the Asics Novablast 5, Adidas Evo SL, Puma Velocity Nitro 4, and Nike's own Vomero 18, to assess its performance in the current market.
The Nike Pegasus 42 is an average update for serious runners, largely functioning as a lifestyle shoe due to its firm and lifeless ride. The full-length Air Zoom unit adds stiffness and marginal energy return, contributing to a 10g weight increase over its predecessor. Its ReactX midsole feels overly firm, providing no real bounce or responsiveness compared to modern alternatives, making it one of the slowest options on the market. If you need a dependable, durable, and stable shoe for casual wear and occasional short jogs, this shoe will be acceptable. However, if you are an up-and-coming runner seeking an inspiring ride for serious training or longer distances, you should look elsewhere.

The biggest, most notable change in the Pegasus 42 compared to version 41 is the addition of a full-length curved Air Zoom unit set within the foam, replacing the smaller front and back units of previous models.
reviewer_claimnegativet=1:15–1:21
The new full-length Air Zoom unit certainly makes the shoe a lot stiffer than the outgoing model. The reviewer found its energy return to be very marginal in his testing.
visual_inspectionneutralt=1:22–1:29
The Pegasus 42 features a slightly different geometry, including a more prominent rocker at the front and a slightly wider forefoot and toe box.
measurement_testnegativet=1:33–1:44
The shoe has an unfortunate weight increase of 10 grams, making it 357 grams for the reviewer's UK size 12, likely due to the new Air Zoom unit.
specification_claimneutralt=1:44–2:08
The price remains £130 in the UK and is $5 more expensive in the USA. The stack height (37mm heel) and 10mm drop are exactly the same as the previous version.
reviewer_claimnegativet=1:46–1:50
The foam remains the same ReactX midsole, which the reviewer describes as definitely quite firm by today's standards and very overly firm and pretty lifeless for running.
reviewer_claimpositivet=3:26–3:58
The first 'like' for the Pegasus 42 is its dependable and reliable nature, being incredibly predictable like the Hoka Clifton, with fans of the series knowing what to expect.
reviewer_claimpositivet=3:58–4:32
The shoe is very comfortable, with a good upper, breathability, lockdown, heel support, lots of padding, and generous width, suiting most runners.
reviewer_claimpositivet=4:32–5:09
The firm foam and relatively low stack contribute to really good stability, allowing confident cornering. The Pegasus has a reputation for good durability, which is expected to continue.
reviewer_claimnegativet=5:17–5:54
The ReactX midsole is criticised for being overly firm and pretty lifeless for running, making it one of the slowest options on the market with no response, bounce, or cushion for picking up pace.
reviewer_claimnegativet=6:03–6:20
The shoe is criticised for being pretty heavy, going the other way in an era where shoes are getting lighter, making it less ideal for serious runners.
reviewer_claimnegativet=6:20–6:42
The reviewer personally would not run long distances (over 60-90 minutes) in this shoe due to insufficient cushioning, stating it wouldn't look after legs well.
comparisonnegativet=6:48–7:55
The Novablast 5 is £5 more, 5mm more stack, 2mm less drop, and 55g lighter. It offers softer, more cushioned foam, a faster, more fun ride for varied paces, but less stability than the Pegasus 42.
comparisonnegativet=7:58–9:27
The Evo SL is the same price, 2mm more stack, 3mm less drop, and a whopping 90g lighter. It's much softer, more responsive, bouncier, and faster than the Pegasus, though also more unstable, making it better for faster runs and racing.
comparisonnegativet=10:38–11:47
The Vomero 18 is £5 more, with 9mm more stack and slightly heavier. It's softer, plusher, bouncier, more responsive, featuring a dual-layer midsole with ZoomX, making it a better option for most Nike runners seeking a more modern ride.
The most notable change in the Pegasus 42 is a full-length curved Air Zoom unit, replacing the smaller units in the 41. It also has a slightly wider forefoot and toe box, a new mesh upper, and a new outsole. However, these updates come with an unfortunate 10-gram weight increase, making it heavier than its predecessor.
The reviewer categorizes the Pegasus 42 as a 'classic daily shoe' suitable for day-to-day wear, commuting, and casual gym use. It can handle various types of runs okay, up to about a half marathon distance for some, but the reviewer personally would not run more than 60-90 minutes in it. Its overly firm and lifeless ReactX midsole lacks the cushioning and responsiveness needed for inspiring daily training or comfortable long runs.
The reviewer highlights the Pegasus 42's comfort, praising its well-designed upper with good breathability, secure lockdown, padded heel and tongue, and generous width. It also offers good stability, stemming from its firm foam and relatively low stack height, allowing runners to corner with confidence. This combination contributes to its dependable and predictable ride.
The Pegasus 42 retains the ReactX midsole foam, which the reviewer finds to be very firm and lifeless. Although it incorporates a new full-length curved Air Zoom unit intended for energy return, the reviewer experienced only marginal improvement and noted that it makes the shoe stiffer. Overall, the cushioning, response, and bounce are considered lacking, especially when compared to other shoes on the market.
Compared to the Asics Novablast 5, Adidas Evo SL, and Nike Vomero 18, the Pegasus 42 is often heavier, firmer, and less responsive. The Novablast 5 offers a softer, more fun, and faster ride. The Evo SL is significantly lighter, softer, bouncier, and faster, though less stable. Even Nike's own Vomero 18, which is slightly heavier but offers much more stack, provides a softer, plush, bouncier, and more responsive experience with its dual-layer ZoomX midsole, making it a better choice for most runners within the Nike brand. The Pegasus typically wins out only in areas like stability and durability for those who prefer a firmer, more grounded feel.
The Pegasus 42 features a generous width in its standard model, with a slightly wider forefoot and toe box compared to its predecessor. Additionally, Nike offers a dedicated wide fit option, though it's listed as a separate product and might be harder to find. This makes the Pegasus 42 a suitable choice for runners with wider feet.
The reviewer concludes that while the Pegasus 42 remains dependable, comfortable, durable, and stable, it has evolved into more of a 'lifestyle shoe' that can accommodate a few runs rather than a dedicated performance running shoe. Its firm, lifeless midsole and increased weight make it less inspiring for serious training or faster paces. For most runners seeking a dedicated Nike running shoe, the Vomero range is recommended instead. The Pegasus 42 is seen as a simple, no-fuss option that will likely be found in outlet stores.

The Nike Pegasus 42 introduces a full-length curved Air Zoom unit, a wider forefoot, new upper and outsole, and a slight weight increase. The shoe retains its ReactX foam midsole, which the reviewer finds firm and uninspiring for running. While praised for its dependability, comfort, durability, and stability, the Pegasus 42 is considered less suitable for serious running, especially for long distances, and is described as heavy compared to modern alternatives. The reviewer extensively compares it to competitor shoes, consistently recommending others for a more dynamic and cushioned running experience, ultimately suggesting the Pegasus 42 is better suited for casual wear with occasional short runs.
