Short verdict: the Nike Pegasus 41 is a conventional everyday road-running shoe built around ReactX foam, separate Air Zoom units in the heel and forefoot, a 10mm drop and a rubber Waffle outsole. It remains a credible discounted buy when its MR-10 fit suits you. The current Pegasus 42 is the clearer full-price choice when you want more forefoot room, a separately listed UK wide fitting and its new curved full-length Air Zoom unit.
This is a source-checked technical review, not a wear test. Zone2 has no retained Pegasus 41 pair, test log, measured mileage or original photographs. Three previous pages presented the standard shoe, an alleged 2E version and the Electric Pack as separate reviews, then made contradictory claims about weight, fit, stability, durability and ride. This rebuild uses exact Nike product records, consolidates the variants and labels Nike performance language as manufacturer description.
Zone2 verdict
Buy Pegasus 41 for: everyday road running when the fit is comfortable and the discount is meaningful compared with version 42.
Choose Pegasus 42 for: the current design, a little more toe and forefoot space, the curved full-length Air Zoom unit, easier access to a named UK wide fitting and a full current size range.
Think twice for: technical trails, waterproof use, runners who want a specialist race shoe, or old stock without clear condition and returns protection.
Main trade-off: version 41 remains a legitimate daily trainer rather than obsolete footwear, but version 42 changes more than the colour. The updated Air layout and last make fit and underfoot feel worth comparing directly.
Nike Pegasus 41 specifications
The figures below are Nike specifications, not Zone2 measurements. Weight depends on sex and sample size, which explains why the old pages produced conflicting numbers when they mixed men’s and women’s references.
| Feature | Pegasus 41 | What the source establishes |
|---|---|---|
| Category | Everyday road-running shoe | Nike’s intended use; not a trail or race-specific model |
| Men’s listed weight | Approximately 297g, UK 9 | Exact current Nike UK sample basis |
| Women’s listed weight | Approximately 251g, UK 5.5 | Exact current Nike UK sample basis |
| Heel-to-toe drop | 10mm | Published for both checked adult references |
| Midsole | ReactX foam | Nike’s named foam; softness was not measured by Zone2 |
| Air system | Separate forefoot and heel Air Zoom units | Different from the full-length unit in version 42 |
| Last | MR-10 | Nike says it is the same last used by Pegasus 40 |
| Upper | Engineered mesh | Nike says it is lighter and more breathable than the previous upper |
| Outsole | Waffle-inspired rubber with flex grooves | Designed for road traction and flexibility |
| Other details | Padded collar, tongue and sockliner; reflective details | Reflective details are not PPE certification |
The Nike UK men’s Pegasus 41 record supplies the 297g UK 9 weight, 10mm drop and construction. The women’s Pegasus 41 record lists 251g in UK 5.5. Those samples should not be averaged or treated as a unisex weight.
Pegasus 41 vs Pegasus 42
| Decision point | Pegasus 41 | Pegasus 42 |
|---|---|---|
| Main use | Everyday road running | Everyday road running |
| Men’s UK sample weight | About 297g, UK 9 | About 300g, UK 9 |
| Drop | 10mm | 10mm |
| Foam | ReactX | ReactX |
| Air Zoom | Separate heel and forefoot units | Curved full-length unit |
| Last | MR-10 | MR-10 2.0 |
| Forefoot fit | Reference point | Nike says there is more space at the toes and forefoot |
| Toe spring | Previous silhouette | Greater toe spring from an updated silhouette |
| UK width choice checked | Historical Wide/Extra Wide references vary by market | Regular and Wide listed on Nike UK |
| Best buying case | Useful saving and proven fit | Price gap is small or the updated fit is preferable |
The current Nike UK Pegasus 42 page lists approximately 300g in men’s UK 9, a 10mm drop, ReactX and a full-length Air Zoom unit. Nike explicitly says the MR-10 2.0 last gives more toe and forefoot room than version 41.
The three-gram difference between the listed men’s samples is too small to make a useful buying decision on its own. The Air layout, fit and price gap matter more. Zone2 has not run-tested the two versions side by side and cannot turn Nike’s “energised” or “propulsive” wording into a measured performance advantage.
What changed from Pegasus 40 to 41?
Nike identifies two headline changes in version 41: ReactX replaces the previous React midsole technology, and the engineered-mesh upper is lighter and more breathable. The MR-10 last remains the same as Pegasus 40.
Nike says ReactX is 13% more responsive than its previous React technology. That is a manufacturer technology comparison, not evidence that every runner becomes 13% faster, uses 13% less energy or prefers Pegasus 41 to 40. Zone2 did not perform an energy-return or running-economy test.
Cushioning and ride: what can be concluded?
The documented construction combines ReactX foam with Air Zoom units in the heel and forefoot. Nike describes the result as smooth and responsive. Those components establish the design; they do not establish universal softness, energy return or comfort.
The old Zone2 pages called the forefoot both firm and plush, made an unmeasured energy-return claim, and assigned the shoe to everything from short runs to a half marathon without a test method. Those conclusions have been removed. Runner mass, pace, foot strike, temperature, surface and preference all affect how the same platform feels.
Use the Pegasus 41 for its stated everyday-road brief when it remains comfortable across the sessions you repeat. Do not infer a fixed distance limit from the model name. Build long-run confidence progressively rather than making race day the first extended outing.
Fit and sizing
Nike identifies the Pegasus 41 last as MR-10, the same as Pegasus 40. That is useful to someone who knows version 40, but it is not proof of a universal “true to size” fit. The upper, sock choice, foot shape and how firmly the shoe is laced still matter.
Try the shoe with normal running socks and check:
- the longest toe has useful clearance when standing;
- the upper does not press or visibly bulge across the widest part of the foot;
- the heel remains seated without painful lace tension;
- the tongue and eye-stay do not create pressure over the instep;
- walking, turning and a short indoor jog feel secure before outdoor use.
Do not automatically size up to solve a width problem. More length can introduce heel movement without creating enough space at the pressure point. A separately constructed wide fitting is the cleaner comparison.
Is the Pegasus 41 available in 2E or wide?
The old Zone2 page confidently called its subject “2E”, but it did not preserve an exact UK product code or primary source. Nike’s regional naming is not consistent enough to treat Wide, Extra Wide and 2E as interchangeable labels without the exact listing.
An official US Pegasus 41 page offered Regular and Extra Wide. An official UK Pegasus 41 By You record labelled the model Wide, but that custom product was sold out when checked. Zone2 could not verify a current standard UK Pegasus 41 product page explicitly labelled 2E.
If a UK retailer describes old stock as 2E, confirm the box and tongue-label product code, compare the retailer’s width description with Nike’s size information and buy only where the pair can be returned unworn. A standard Pegasus with a little toe room is not automatically the same construction as a wide model.
The current Pegasus 42 has a separately listed men’s Wide version on Nike UK. It also has more forefoot and toe room than version 41 in the standard last, but that relative change is not a guarantee for every wide foot.
What was the Pegasus 41 Electric Pack?
The Electric Pack was a colourway, not a separate Pegasus performance model. Nike launched the design on 24 July 2024 across 55 footwear styles. It combined Total Orange with an ostrich-inspired print associated with the Air Safari.
Nike’s regional Pegasus 41 Electric product record lists the same core road-shoe construction: ReactX, heel and forefoot Air Zoom units, engineered mesh, Waffle outsole, MR-10 last and 10mm drop. The Electric article therefore does not need its own independent performance verdict or canonical URL.
When buying an Electric pair, decide on colour, condition, authenticity, size and price. Do not pay more because an old review implied that the colourway produced better energy return, support, traction or durability. Nike’s Electric Pack launch record describes the design programme rather than a Pegasus-specific mechanical upgrade.
Upper and breathability
Pegasus 41 uses a single-layer engineered-mesh upper. Nike says it reduced weight and increased breathability relative to the previous iteration. Plush padding appears at the collar, tongue and sockliner.
Zone2 did not measure airflow, water absorption or drying time. The upper is not described as waterproof, and reflective design details are not personal protective equipment. For dark road running, combine footwear with active lighting and route choices rather than treating reflective shoe accents as complete visibility protection.
The Zone2 reflective running-jacket guide explains the difference between reflective material and active light. Choose a separate waterproof model if a membrane is genuinely required.
Outsole, grip and British weather
Nike specifies a Waffle-inspired rubber road outsole with grooves for flexibility. It does not publish a wet-friction score, lug depth or comparison with trail compounds. That makes the useful verdict straightforward: the outsole is designed for roads, not mud, technical trail or ice.
Rain does not automatically require waterproof shoes, but wet painted markings, metal covers, polished paving, algae and fallen leaves can reduce grip. Slow down or change the route when the surface is doubtful. For regular mixed trails, select trail in the shoe matcher rather than stretching a road-shoe review into a terrain guarantee.
Durability and replacement
Nike describes the ReactX foam as durable and the Waffle outsole as providing durable road traction. Zone2 has no retained mileage log, wear photographs or controlled abrasion test for Pegasus 41, so this guide does not promise a particular lifespan.
Inspect the actual pair. Smooth tread, exposed midsole foam, a collapsed heel counter, split upper, compressed or uneven platform, damaged lining and new discomfort are more useful than an unsupported universal mileage number. Old stock also deserves a check for hardened foam, sole separation and poor storage.
Pegasus 41 for walking, gym and daily wear
The secure padded upper, road outsole and everyday-running construction make Pegasus 41 a plausible walking shoe when it fits. That does not make it certified workwear or an ideal lifting platform. The product page explicitly says reflective details are not PPE.
For ordinary walking, use the running-shoes-for-walking guide to check fit, terrain and condition. For heavy lifting or lateral court work, use activity-specific footwear rather than assuming one running shoe covers every movement.
Who should buy Pegasus 41 now?
- Good match: an everyday road runner who knows the MR-10 last fits and finds genuine version 41 stock at a useful discount.
- Good match: a Pegasus 40 user who wants ReactX while retaining Nike’s stated last shape.
- Possible match: someone comparing an authenticated Wide or Extra Wide version with a clear return option.
- Poor match: someone paying close to version-42 money without preferring the older fit.
- Poor match: runners needing a waterproof, mud-specific, technical-trail or race-specialist shoe.
- Poor match: clearance stock with unclear age, style code, condition or returns protection.
To compare the current model with other daily trainers, open the Zone2 matcher pre-set for a balanced neutral road shoe. For a current wide shortlist, change the width filter to Wide required. The scoring uses manufacturer data, shows compromises and has no paid placements.
Frequently asked questions
Is Nike Pegasus 41 good for running?
It is designed for everyday road running. Whether it is good for you depends on fit, comfort and the sessions you plan to repeat. Zone2 has not wear-tested it and does not claim a universal distance or pace range.
How much does Pegasus 41 weigh?
Nike UK lists approximately 297g for a men’s UK 9 and 251g for a women’s UK 5.5. Always compare figures with the sex and sample size attached.
What is the Pegasus 41 heel-to-toe drop?
Nike lists a 10mm drop for the checked men’s and women’s references.
Does Pegasus 41 use ReactX?
Yes. The ReactX midsole surrounds separate Air Zoom units in the heel and forefoot.
Is Pegasus 41 a neutral shoe?
Nike presents it as a responsive everyday road shoe and does not identify a dedicated guidance system on the checked product records. A category label cannot diagnose how an individual will move or what support they need.
Is Pegasus 41 true to size?
Nike says it uses the same MR-10 last as Pegasus 40. That is useful continuity, not a universal sizing guarantee. Try the exact width with normal socks and check toe room, midfoot pressure and heel hold.
Is Pegasus 41 good for wide feet?
Wide and Extra Wide references existed in official regional records, but availability and naming vary. Zone2 could not verify an active standard UK page explicitly labelled 2E. Confirm the exact product code and return terms.
Is the Pegasus 41 Electric different?
Its Electric Pack treatment is a colourway. Nike’s product record retains the core Pegasus 41 road-running specification rather than documenting a separate performance platform.
Is Pegasus 42 better than Pegasus 41?
It is newer, not universally better. Version 42 adds a curved full-length Air Zoom unit, updated last, greater toe spring and more toe/forefoot room. Version 41 can still be better value when its fit is proven and the discount is meaningful.
Can you use Pegasus 41 for a half marathon?
Nike specifies everyday road running rather than a fixed maximum distance. A half marathon is plausible only after the shoe has remained comfortable through progressively longer training. The old Zone2 half-marathon recommendation was not based on a recorded test.
Final verdict
The Nike Pegasus 41 is a legitimate everyday road trainer with clearly documented ReactX foam, dual Air Zoom units, a 10mm drop, engineered mesh and a rubber Waffle outsole. Its exact men’s and women’s weights are 297g in UK 9 and 251g in UK 5.5 on the checked Nike records.
Buy version 41 when its MR-10 shape works and the price advantage is real. Choose Pegasus 42 when you prefer its roomier updated last, full-length Air unit or current UK wide availability. Treat Electric as a colourway, verify any 2E claim against the exact product label, and ignore the old unsupported promises about fit, energy return, stability, distance and durability.
