Pegasus Plus 2 vs Pegasus 42: Which Nike Shoe?

If you are choosing between the Nike Pegasus Plus 2 and the Pegasus 42, the Pegasus Plus 2 is the better choice for daily training and longer runs, while the Pegasus 42 is the more versatile and affordable option for general use. The Plus 2 uses a softer, more energetic foam and a lighter build, whereas the 42 is firmer, more durable, and better suited for those who want one shoe for everything. Below is a detailed comparison of their features, performance, and fit to help you decide.

Formula

This calculator works out your average running pace and speed from a given finish time and distance. The formulas are:

• Pace (min/km) = Total time in minutes ÷ Distance in kilometers
• Speed (km/h) = Distance in kilometers ÷ (Total time in minutes ÷ 60)

Where t is the total time in minutes, d is the distance in kilometers, pace is expressed as minutes per kilometer, and speed is kilometers per hour.

Worked Example

Using the default values: you run 10 km in 50 minutes.

1. Pace = 50 min ÷ 10 km = 5.00 min/km
2. Speed = 10 km ÷ (50 min ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator returns a pace of 5.00 min/km and a speed of 12.00 km/h.

Background: Two Different Approaches to the Pegasus Line

The Nike Pegasus has been a staple of daily training for decades, but the Plus 2 and the 42 represent two distinct philosophies. The Pegasus 42 is the traditional workhorse: a reliable, moderately cushioned trainer with a rubber outsole that lasts hundreds of miles. The Pegasus Plus 2, introduced as a premium variant, swaps the standard foam for Nike’s lighter and bouncier ZoomX foam, which is the same material used in the Vaporfly racing shoes. This makes the Plus 2 feel noticeably softer and more responsive, but it comes with a higher price and a less durable outsole.

How the Shoes Differ in Cushioning and Ride

The most significant difference is the midsole foam. The Pegasus 42 uses a combination of Nike’s React foam and a Zoom Air unit in the forefoot. This gives a firm, stable, and slightly springy ride that works well for most paces. The Pegasus Plus 2 replaces React with ZoomX, which is much softer and more energy-returning. On the run, the Plus 2 feels plush and bouncy, almost like a racing shoe, while the 42 feels more grounded and connected to the road.

For a runner who wants to feel the ground and prefers a traditional trainer, the 42 is the safer pick. For someone who wants maximum comfort and a lively push-off, the Plus 2 is clearly superior. However, the softness of the Plus 2 can be less stable for runners with weak ankles or those who overpronate, as the ZoomX foam compresses more under load.

Weight and Upper: Which Feels Lighter on Foot?

The Pegasus Plus 2 is lighter than the 42 by roughly 20-30 grams (about 0.7-1 ounce) per shoe, depending on size. The Plus 2 uses a thin, engineered mesh upper with fewer overlays, which improves breathability and reduces weight. The 42 has a more traditional padded upper with a thicker tongue and heel collar, offering more lockdown and warmth but also more bulk.

In practice, the Plus 2 feels more like a racing flat in the upper, while the 42 feels like a classic daily trainer. If you run in hot weather or prefer a barely-there feel, the Plus 2 wins. If you like a snug, secure fit with extra padding around the ankle, the 42 is more comfortable.

Durability and Outsole: Which Lasts Longer?

Here the Pegasus 42 has a clear advantage. It features a full rubber outsole with a waffle pattern that provides excellent traction and wears very slowly. Many runners report getting 500-700 miles (800-1100 km) from a pair of Pegasus 42s. The Plus 2, in contrast, uses a thinner rubber layer on the forefoot and heel, with exposed foam in the midfoot. This reduces weight but makes the outsole less durable. Expect around 300-400 miles (480-640 km) from the Plus 2 before the foam starts to degrade.

If you are a high-mileage runner who wants a shoe that lasts a full training season, the 42 is the more economical choice. If you prioritize performance over longevity and are willing to replace shoes more often, the Plus 2 is acceptable.

Fit and Sizing: Do They Run the Same?

Both shoes fit true to size for most runners, but there are subtle differences. The Pegasus 42 has a standard width and a slightly roomier toe box, accommodating most foot shapes. The Plus 2 has a more snug, performance-oriented fit, especially in the midfoot and heel, which can feel narrow for wide-footed runners. If you have wide feet, the 42 is the safer option, or you may need to go up half a size in the Plus 2.

Also note that the Plus 2’s upper is thinner, so it may require a bit more breaking in for the laces to settle. The 42 is comfortable out of the box.

Price and Value: Which Gives You More for Your Money?

The Pegasus Plus 2 typically retails for about $40-50 more than the Pegasus 42. The 42 is often found on sale, making it one of the best-value daily trainers on the market. The Plus 2’s higher price is justified only if you specifically want ZoomX foam and a lighter shoe. For most runners, the 42 offers 80% of the performance at 70% of the cost, and it lasts longer. If you are on a budget or run high mileage, the 42 is the smarter purchase. If you want the premium feel and are okay with replacing shoes more often, the Plus 2 is worth the premium.

Common Problems and Misconceptions

A common misconception is that the Pegasus Plus 2 is simply a faster version of the 42. In reality, the Plus 2 is softer and more cushioned, but not necessarily faster for all runners. Some runners find the ZoomX foam too squishy for tempo runs or intervals, while the 42’s firmer foam provides better ground feel for speedwork. Another issue with the Plus 2 is that the exposed foam on the outsole can pick up small stones and get cut easily on rough terrain. The 42’s full rubber outsole is more robust.

Also, some runners experience heel slippage in the Plus 2 because the heel collar is less padded. If you have narrow heels, you may need to use a runner’s knot (lacing through the top eyelet) to secure the fit.

How to Choose: A Simple Decision Guide

• Choose the Pegasus Plus 2 if: you want maximum cushioning, a bouncy ride, and a light shoe for long runs or recovery days.
• Choose the Pegasus 42 if: you want a durable, versatile trainer for daily miles, tempo runs, and occasional races, especially if you prefer a firmer feel.
• Choose the 42 if you have wide feet or want a shoe that lasts 500+ miles.
• Choose the Plus 2 if you are willing to spend more and replace shoes more frequently for the premium foam.

Frequently Asked Questions

Are the Pegasus Plus 2 and Pegasus 42 the same size?

Both shoes generally fit true to size, but the Plus 2 has a narrower, more snug fit, especially in the midfoot. If you have wide feet, consider the 42 or go up half a size in the Plus 2.

Which shoe is better for marathon training?

For marathon training, the Pegasus Plus 2 is better for long, slow runs due to its plush cushioning. However, the 42 is more durable and can handle the high mileage of a marathon block without breaking down as quickly. Many runners use both: the Plus 2 for easy days and the 42 for everything else.

Can I use the Pegasus Plus 2 for racing?

Yes, but it is not a carbon-plated super shoe. The Plus 2 is lighter and bouncier than the 42, making it suitable for shorter races like 5K or 10K, but for a marathon, you would likely want a dedicated racing shoe like the Vaporfly or Alphafly.

Which shoe has better grip on wet roads?

The Pegasus 42 has a more aggressive rubber pattern and more coverage, so it generally offers better traction on wet surfaces. The Plus 2’s thinner rubber can be slightly less grippy, especially on slick pavement.

Is the Pegasus 42 good for walking?

Yes, the 42 is a comfortable walking shoe due to its firm, stable midsole and durable outsole. The Plus 2 is also fine for walking, but its soft foam may feel unstable for all-day standing.
