Matt Rufthafordwrote a review of Saucony Peregrine 7 Trail Running Shoe - Men's on June 23, 2017
Familiarity: I've put it through the wringer
Fit: True to size
After putting just shy of 50 miles on these shoes (rough New England mountain running) I love almost everything about them. Almost.
My arches are on the lower side of the spectrum, my feet are pretty low volume, and pretty narrow. So I was a little worried that the additional volume in the forefoot compared to what I was used to (La Sportiva Helios V1, La Sportiva Akasha, La Sportiva, La Sportiva...) would be a problem. It hasn't been. I've actually really enjoyed the extra room.
The greatest thing about these shoes is the tread. I have never been one to go for a super nobby outsole and these are far more aggressive than anything I've ever used. But I have a race coming up with lots of technical climbing and descent as well as a fair amount of ski trails so I thought I'd give it a shot. These. Things. Are. Awesome. Ski trails - it'll stick. Buffed trail - it'll stick. Textured schist/granite - it'll stick. The only time I'll be a bit cautious is on wet rock, but that's true of most shoes, especially those with nobby outsoles. Other than that, I feel super comfortable flying down trails and charging up as hard as I can.
My feet also sweat a good deal and while there are a lot of welded overlays on the sides (makes for decent protection when I'm wedging my foot for purchase) the forefoot breaths super well. I'll regularly feel the breeze straight through the shoe.
The sole is also thick enough that I don't feel like I'm really beating my feet up as I run down the trail. That is also likely helped by the rock plate. And the fact that the shoe is pretty light also means that I feel nice and agile as I'm hopping up, over, onto, around, etc everything. I was able to cruise down trail with the Akashas too but the extra weight and the bulkiness made them feel a lot less nimble.
The one thing that drives me nuts (sometimes). The top of the midsole inside the shoe. It gives great support but it's also kind of slick. Every time my feet get dunked in a stream and I end up on some steep downhill (25% grade or steeper) then my insole will start to slide around. Eventually, it'll fold over on itself which is super annoying. And once it happens, it won't stop happening for the rest of the run. I've tried three insoles now and the third one has yet to get wet enough to see if the problem is resolved. I've read the same thing in other reviews. I may just super glue them down and be done with it.
Overall, totally recommend them. Just be aware of that one issue.
