Timp 6

Sadly the Timp is too narrow for me. The Topo Pursuit 2 is on the list and I will try it as soon as I get my hands on a pair. I tried several Altras (Timp 6, Olympus 6, Mont Blanc, Olympus 275), but none was a match.

I have trouble finding the right zero drop/wide toe box shoe. I am happy with my Altras on the road, like Paradigm 6 and Torin 8. I currently run on Lone Peak 9+, which fits perfectly fine, but I just wish it had more cushioning. I tried Timps, Mont Blancs, Olympus 6, Opympus 275…either issues with heels or too narrow.  Then again I wonder if I would be happy with more cushioning at all on technical trails. I just finished my first self sustained marathon (43km/1500m vert) and it didn‘t feel bad, there is just the little voice that tells me that I might be wrecking my joints too much in the long run (pun intended). 

I think you'll have better luck asking in r/AltraRunning There will be more people who actually know about these two models there, but also they don't mind answering q's about similar shoes in my experience. But to answer your original question, I've been trying on the GTX shoes from Altra trying to find a pair for winter. They used to waterproof their non gore tex models but they don't seem to anymore. I have really wet slushy conditions where I live. The snow clung to my LP7 and made my feet too cold. The GTX LPs are made on the same base/outsole, but the upper material itself isn't as flexible. Like someone else said, it's more snug. But also the upper seems to be slightly different. I tried on the Timp 6 GTX versus the Timp 6 and I was so disappointed that they moved the heel collar just enough so that it rubbed my ankle knots, whereas the non GTX version did not. I don't know if that's the case with LP, it's just a heads up. Also my experience with gore tex is that it's a more fragile fabric, so it's more prone to failure. It's not breathable, either, so if you get sweaty, you stay sweaty.

Also check out the Altra Olympus. I prefer them over the Timp for days I want cushion.

Those shoes gave me the worst plantar fascia issues and I hated that I couldn’t heel lock the laces. I switched to the Altra Timp 6 and have had zero issues

I've been hiking/backpacking and running in various Altras for over 5 years. In my experience the Timp and Lone Peak performed better as hikers, the Mont Blanc was better as a runner, and the Olympus 275 has been a great middle ground. It's got the higher stack and rocker toe from the Mont Blanc, but is still plenty stable thanks to the wider footprint that is more similar to a Lone Peak. Since you specifically asked for other suggestions: * The Mount to Coast H1 is having a moment right now and is a road-to-trail running/hiking shoe. I don't have any personal experience but there are countless glowing reviews of it around. * I recently bought a pair of the Norda 001a and have been loving them so far. I only have about 25 miles on them from runs in South Mountain and the Superstitions, but I'm pretty confident they'll replace my Olympus 275 pair with ~400 miles on them as my "do it all" shoe as I get more time in them.

I haven't run in the Lone Peak, but I routinely get over 300 miles out of the Timp. I'm 6'5", 180, for reference.

Great shoe but it'll beat your feet up on a hundo if you're not accustomed to it. I recommend Mont Blanc Speed or new Timp.
