Product Highlights:
The Nike Pegasus 42 GORE-TEX takes the versatile, reliable daily trainer that generations of runners trust and adds weather-ready protection so you can keep logging miles without worrying about wet conditions. While the standard Pegasus 42 already delivers a lively ride for beginners through elites, the GORE-TEX version ensures your feet stay dry and comfortable when rain or damp roads try to interrupt your routine.
While its ReactX midsole foam is slightly lighter than before, its new full-length Air Zoom unit is the key highlight. Learning from the Pegasus Premium's Air unit, it improves on the Pegasus 41's separate units to deliver a smoother and more responsive experience. Altogether, this new midsole delivers over 15% more energy to your routine weekly runs and moderate tempo work.
A waterproof yet breathable GORE-TEX upper creates a dry, comfortable environment inside the shoe, sealing out moisture while allowing heat and humidity to escape so your feet don't overheat on longer efforts. The familiar Pegasus fit remains, with a plush tongue, soft internal lining, and midfoot band that delivers lockdown without feeling restrictive. An updated waffle outsole concentrates durable rubber where you need grip most and adds flex grooves for reliable traction on wet or dry surfaces.
For years, the Pegasus has been the dependable choice for everyday training. The Nike Pegasus 42 GTX builds on that legacy with fresh energy, smoother propulsion, and the confidence to head out in any weather.

Stack Height
Stack Height
Stack height refers to how much shoe is between your foot and the ground. For this category, we reference the amount of material below the forefoot, as the heel height will be equal to or greater than the forefoot height.
Learn more about stack heights and how we measure them.-
Minimal
14-18 mm. The shoe has a thin midsole that allows for a natural running experience. Classic racing flats and minimalist shoes are common here. These shoes offer a feeling of being directly connected to the road or trail.
-
Low
19-23 mm. The shoe has a slightly cushioned feel and might feature additional midsole technologies. Performance training shoes and some trail shoes are common here. These offer some protection during foot strike but prioritize a lightweight, grounded experience.
-
Medium
24-28 mm. These shoes have a stack height that falls near the middle of the spectrum. The shoes in this category are versatile and great for almost all types of runs and distances.
-
High
29-34 mm. The shoe has a thick midsole and ample cushioning. These shoes are highly protective and absorb more of the impact you experience.
-
Maximal
35 mm plus. The shoe has an extremely thick midsole and extra cushioning. The focus is on maximum protection underfoot, often with a plush experience for hardly any ground feel. Some pinnacle racing and performance shoes can also be found here.
How We Measure Our Shoe Specs
-
We measure every shoe in-house to provide accurate and consistent details.
-
Weight
Weight is measured per single shoe, including laces. Men's and unisex styles are based on a men's size 9, and women's styles are based on a women's size 8.
-
Heel Stack
The heel stack refers to how high your heel sits above the ground when wearing shoes. Based on Men's size 9 as the standard.
-
Forefoot Stack
Forefoot stack refers to how high the ball of the foot sits above the ground when wearing shoes. Based on Men's size 9 as the standard.
-
Heel-toe Offset
Heel-toe offset (drop) is the difference in height between the heel stack and the forefoot stack. We use the number given to us by the brand.
How We Measure Shoe Fit
-
All measurements are based on Medium width. Note: fit is relative to the "average" running shoe.
-
We partner with SmartLast, a program by Heeluxe, to use advanced shoe-measuring technology, to provide objective measurements for toe box, midfoot, and heel widths as well as overall length.
