Peregrine 15

I have a pair of Saucony Peregrine 15s which at first I found uncomfortable, before I realised that my real issue was my socks rather than my shoes. They're optimised for mud but resilient enough to run along the roads at a fair lick between trails, and comfortable enough for rocky terrain. Great at letting water back out too. I've worn them for the Seventh Seal 50k and the Ranger Ultras Peak District North with no complaints

I agree with what @eastsidegrind said. And I think maybe you mean “a stable shoe” rather than “a stability shoe.” Stability running shoes provide structured support for runners who overpronate (feet roll inward excessively), to guide the foot into a more neutral, aligned stride, using features like firmer foam, guide rails, or extra arch support in the midsole. They offer a more balanced, supportive ride for those with flexible arches or who experience form breakdown when tired, unlike neutral shoes, which lack this built-in correction. It seems you are looking for something that is simply more stable under your feet so you don’t turn your ankle, etc. In the last few years, I had a pretty decent roll of my ankle, and now it keeps happening. I’ve noticed that it happens more often on a flat road with my Saucony Triumph 20s than it does on trails with my Saucony Peregrine 15s. The Peregrines are 10-13mm lower overall than the Triumphs, with a 4mm drop vs 10mm. Not trying to sell you on Saucony, but you get the general idea. I really honk I was rolling my ankle because of the Triumph’s overall height, and I feel really “stable” in the Peregrines, even though I use the Peregrines in much more uneven terrain. So, IMO, you should look at shoes with a lower overall height for a more stable run. (Unless, of course, I was wrong and you actually are wanting a true “stability shoe”)

I only got 180mi on my Peregrine 15s before the inside stitching around the heel split and the shoe lost all of it's structure. SG5s also didn't last long for me (the upper splits where it meets the midsole), but were great for the first 200mi. I'm onto Mount To Coast T1s and enjoying the combination of toe box width, traction, and stability (despite being a decent stack height of PEBA).. will report back on the longevity in a couple months.

I've run those trails and in Speedgoats and Ultraventures, either would be fine. If you're running the 50K, the Peregrine could work too. It's a good idea to have 2 pairs, and I'd rather use both in training so they feel the same for race day. 1 pair will work fine a lot of the time, only consideration would be if you had 300 miles of trail training before race day or something like that, maybe not ideal to start a race with busted shoes.

I’d say the width was the same as my Peregrine 15’s which are tight and the issue I’m having is over about 15km my smaller toes are getting really sore. I was trying to replace them with something else that would also have good grip but wanted something wider. Unfortunately it wasn’t the Tomirs. I ran 34km in the Peregrines yesterday and my toes hate me right now. In the UK you have to order Mount to Coast direct from their website and they ship from China in around a week. A bit annoying you can’t try them on easier with how different sizing is brand to brand. Oh and if you order some I found a discount code on YouTube CRAIG10 for 10% making the H1’s £135 and you get a free pair of socks and free shipping
