Our verdict

A beast in all our trail runs, the Saucony Peregrine 11 was more than confidence-inspiring! It's a tank that mutes out all the harshness of the trails while eating up everything you throw at it! From slick mud, snow, dry, and rocky stream crossings, this shoe just bites hard and deep into the ground. It's also able run fast, and we got exactly that in the Peregrine!


  • Outstanding grip
  • Perfect foot lockdown
  • Great for mud, ice, rocks
  • Durable as a tank


  • For narrow feet only
  • Not breathable
  • Heavy

Saucony Peregrine 11 review and lab test

Great winter shoe for people with narrow feet. 

The Peregrine 11 is a heavy-duty trail shoe with grip, durability, and performance as its focus. This shoe is ideal for the runner that wants to smash trail regardless of the terrain and yells from the trailhead “ground feel be damned!” 

I don’t know if that’s anyone's battle cry in the real world, but these shoes are stiff underfoot, heavily padded in the upper, and wrapped in thick rubberized overlays to keep the elements out. I’ll say it again too, the grip is outstanding!Pieces of the Saucony Peregrine 11

Don’t buy this shoe if you have wide feet or if you are looking for 

  • a lightweight trail shoe with flex (have a look at Saucony Switchback 2 then), 
  • high breathability, or 
  • the ability to feel what’s underfoot (Saucony Ride 15 is worth checking out in this case). 

If you’ve gone down the path of minimalist shoes at all and enjoyed it, the Peregrine 11 will be a step in the opposite direction. 

Perfect lockdown: the reason to buy this shoe

Lockdown was amazing and Peregrine 11 is confidence-inspiring on steep fast trails since there are virtually zero movements once the shoe is laced up tight. This is what this shoe is built for. 

I was impressed that I didn't have any heel slip, normally super-stiff heel cups (77.5N, compared to the average runner being just 62.2N) don’t work for me, but it did on the Peregrine 11. 

Most likely it's because the upper is so stiff, once locked down over the midfoot, thanks to the tensioned overlays and thick, somewhat stretchy gusseted tongue, there's no way your heel is moving around. 

Comfort failure: too narrow & too stiff 

If I was going to compare these to ski boots… Haha just kidding, we all know ski boots are not comfortable at all, but that pain has a purpose, and I felt that way with the Peregrine 11. 

I had issues with the fit of the Peregrine 11. It’s built on a narrow platform, at 107.9mm under the forefoot, it's the skinniest shoe upfront we’ve tested and well under the average of 113.4mm. Mix that with a very stiff upper that doesn’t have much flex and my feet were hurting the first two runs.

This is not just an upper concern, the midsole is stiff too, at 34.7HA on the durometer it’s 27% stiffer than the average shoe in our test. 

They are able to grip, and part of that is a tight, stiff upper, I just didn’t need this level of performance and prefer my trail runners to be a bit plusher. 

It took a while to break in, and I even cut my first run short because my feet were cramping up. 

Outstanding grip: you will trust Saucony Peregrine 11

I’ve mentioned this above in the ride section, but man, the grip is amazing.

I pushed them hard through everything I could, including slick mud, snow, and over dry, rocky stream crossings, and they were confidence-inspiring. 

We don’t get a ton of mud here in Colorado, so I’m not sure if I’ll need these come mid-summer, but on softer terrain, they excel!

Too warm to be your summer running shoe

Although the Peregrine 11 is technically made from mesh, I would not call these highly breathable.

They felt warm, even on a cool spring day in the mountains, and with the rubber overlays, I don’t think come July I’d pick this shoe unless I was at higher elevations. 

Generous padding certainly didn’t help. There’s plenty of padding in the upper, the tongue alone is 11mm thick, double that of our average measurement of 5.5mm. 

The ankle collar follows suit as well with more padding than almost any other shoe we’ve put through the RunRepeat lab at 9.6mm, 14.4mm, and 15.9mm (front, middle, back of the ankle collar).

In our lab, we perform a transparency test to see how much light goes through the upper. Peregrine 11 let only 2.2LUX through. The average we have so far? 100.9LUX! 

This means it could be a great winter shoe. It has built-in gaiter attachments, at least on the toe, none on the heel.

You can attach the gaiters to the stretchy horizontal heel loop on the back of the shoe, but there’s no velcro tab which I’d prefer. 

Peregrine 11 crushes everything under your feet

Looking past the fit and comfort issues, the ride is amazing. I say this because the grip is amazing. 

The ride itself is stiff, and there’s no ground feel, but because this shoe grips so well I found myself tearing down muddy, icy, rocky, rooty trails at full speed, coming into blind, 180-degree turns with steep drop-offs without the need to slow down. 

Talking about stiffness, even in our lab the shoe took 33.6N to be flexed. Compared to the average of 26.2N for the other shoes we’ve had in our lab, it definitely sits on the stiffer side. 

This comes from the deep, sharp, widely spaced, multi-directional lugs. Saucony says they are 6mm deep, but I found that number to include the whole outsole, the lugs themselves are just 4.35mm deep, which is still the deepest we’ve tested so far.

It’s also touted as a 4mm drop shoe, I got 5.1mm on our measurements, but still, it’s flatter than some trail shoes and I like how that balances these shoes out on difficult terrain. 

It’s fun to run, it’s fun to forget about everything but going fast. I wish I could have gone 10 miles, but after about 2-3 miles my feet had had enough. 

They can go fast on technical gnarly trails. You don’t need the Peregrine 11 to coast along on breeze trails in your local town park, they do well in going up and down varied terrain, and would even be a great off-trail option. 

Adaptation period: a must

Unfortunately, these shoes need miles to open up. Not to harp on my skiing metaphor too much, but I felt like that guy with race boots that you see sitting by the fire in the lodge after just 2 runs with his boots off, rubbing his tire arches.

They did start feeling better after some abuse, but they are stiff. There’s just no flex in the upper either, and the midsole locks you to the ground, not spring you off it. 

Too heavy with no excuses

They are heavy, at 11.2 ounces (318g) I’m surprised it's called the Peregrine and not the Dodo. 

Weight of Saucony Peregrine 11

Here’s a shortlist that adds up: 

  • A 6mm outsole with lugs that can climb Everest, 
  • stiff upper with tons of padding that’s 1.8mm thick where the heavy overlays are, 
  • a rigid 2mm thick plastic heel counter (thickest we’ve tested), and 
  • an 11mm padded tongue.

I’d like to try to justify the weight by saying, “but they are packing a lot into this shoe” but I really can’t, they are heavy.

Peregrine 11 is durable as a tank

The Peregrine is built like a tank. The welded overlays are covered in thick rubber, blocking out the elements and the inevitable rubbing wear that comes from running in the dirt.

I think they will go much further and last much longer than your feet may want them to!


Ultimately, the Peregrine 11 is a high-performance shoe that can go fast. The name says it all! It grips amazingly well, it instills a confidence that’s unsafe at times, and although my wider feet didn’t love the fit, it has a place. If I was living in the PNW or somewhere that saw more wet and muddy trails, I’d want a shoe like this.

But for me, it’s just too stiff and narrow to stay in my daily rotation, and although I love the way it looks, and the emotion it alludes to (yes I read My Side of the Mountain as a kid), I wish it was less of a race ski boot, and more something the masses could enjoy.
