The Pegasus Trail 5 GTX might be Nike’s smartest waterproof running shoe yet—somehow lighter than the regular version despite adding Gore-Tex protection. After extensive testing through rain, stream crossings, and muddy trails, I’m convinced this delivers something genuinely useful rather than just another waterproof variant. Though it’s not without trade-offs, and perhaps those limitations keep it feeling honest. See how the Pegasus Trail 5 GTX compares to other waterproof sneakers in our complete buying guide.
Design & Upper
The first surprise is visual—this doesn’t look like a typical waterproof trail shoe. The Gore-Tex Invisible Fit technology integrates the membrane so seamlessly that it maintains the sleek aesthetic of the regular Pegasus Trail 5. The engineered Flyknit upper feels remarkably flexible for a waterproof construction, avoiding the stiff, plastic-like feel that plagues many Gore-Tex shoes.
What’s clever is the built-in ankle gaiter—it’s subtle enough to work with jeans but functional enough to keep debris out during trail runs. The redesigned heel tab includes a finger loop that makes these easier to slip on. And those reflective elements? They’re integrated throughout rather than just slapped on, which shows attention to detail.
The upper construction surprised me with its lightness. At 9.9 oz, it’s actually 0.2 oz lighter than the standard Trail 5, which shouldn’t be possible but somehow is. Nike achieved this by removing padding in non-critical areas while maintaining structure where it matters.
Waterproofing
The Gore-Tex implementation is genuinely impressive here. Lab testing shows essentially zero breathability (1 out of 5), but that’s the trade-off for complete waterproof protection. The fully gusseted tongue creates a proper seal, and the ankle gaiter adds another layer of protection.
Real-world testing through stream crossings, puddles, and extended rain exposure showed zero water penetration. The membrane feels robust yet thin—under microscopic examination, it’s densely woven but not bulky. This balance makes the shoe suitable for wet conditions without the cumbersome feel of traditional waterproof footwear.

The downside is predictable: your feet will run significantly warmer than in regular mesh shoes. This isn’t summer footwear unless you’re running in consistently wet conditions.
Traction & Running Feel
The All-Terrain Compound (ATC) outsole carries over from the standard version, and it works well for mixed terrain. The 3.2mm lugs provide solid grip on moderate trails without feeling clunky on roads. Lab testing shows improved traction compared to previous Pegasus Trail versions, particularly on wet surfaces.
The ReactX foam midsole is where things get interesting. Measuring 51.5% softer than average trail shoes, it provides significant cushioning while maintaining responsiveness. The rocker geometry promotes smooth heel-to-toe transitions, making road-to-trail transitions feel natural.
At 37mm heel and 27.5mm forefoot (actual measurements), the stack height provides substantial impact protection. The 9.5mm drop works well for heel strikers but may feel tall for midfoot or forefoot runners.
The midsole flexibility (29% more flexible than average) allows natural foot movement while maintaining structure. This balance makes it comfortable for longer runs but potentially less supportive on technical terrain.
Best Use Cases
This excels as a year-round training shoe for runners who encounter varied conditions. If you run roads, bike paths, and light trails—especially in wet climates—the versatility is genuinely useful. It handles stream crossings confidently and transitions between surfaces smoothly.
For travel, it’s particularly practical. One tester used these extensively in Thailand, covering 50+ miles of varied terrain with excellent results. The combination of road capability and trail protection makes it ideal when you need one shoe for multiple activities.
Pros:
- Gore-Tex Invisible Fit is genuinely waterproof
- Surprisingly lightweight (9.9 oz)
- Excellent traction on wet and mixed surfaces
- ReactX foam provides comfortable and responsive cushioning
- Versatile for road-to-trail running and travel
- Subtle ankle gaiter keeps out debris
Cons:
- Limited breathability leads to warmer feet
- Durability concerns around 300 miles
- Not ideal for technical trail running
- Runs a bit narrow
The Verdict
The Pegasus Trail 5 GTX succeeds as a versatile, waterproof training shoe that doesn’t compromise too heavily on performance. It’s not perfect—durability concerns and limited breathability are real issues—but for its intended use case, it delivers genuine value. Sometimes the best gear is the stuff that just works reliably, day after day, rather than being revolutionary.
Best for: Mixed-terrain running, wet weather training, travel, road-to-trail transitions
Skip if: You prioritize technical trail performance, need maximum breathability, or have wide feet
Compared to the Hoka Challenger 7 GTX, the Pegasus Trail 5 GTX feels more nimble and road-capable, while the Hoka offers superior cushioning and stability for longer trail miles. The Nike is better for faster-paced running; the Hoka excels for all-day comfort.
