Altra has the Superior and King Mtn, both of which have less cushioning and arch support than the Lone Peaks. The Superior 6 is my go-to right now. I train almost exclusively in Xero Prios. I also run in Mesa Trail IIs with a rock plate.
\+1 for the Altra Trail Superior 6. I think the Superior 7 is the latest version, but got a great deal on the 6 :)
I know what you mean by the old NB Minimus line. I LOVED my original minimus trail. They were the perfect shoe IMHO. Currently I use the Altra Trail Superior 6. But I think if you wanted to be as minimal as the old NB Minimus then perhaps something from VivoBarefoot like the Primus Trail FG 3.5. Xero shoes has some pretty packable ones as well
Same thing happened to my speeds at just over 200 miles, REI took them back. I've been in Altra for a few years but starting the transition to something more durable. I'd get 200 miles out of most pairs and they'd either fall apart or I'd start to get these little injuries.
Altra uses 3 different foot shapes, not all their models use the same shape. https://www.altrarunning.com/en-us/about-us/footshape.html. I started off w/ the Altra Lone Peaks then didn't understand why i didn't like their Superiors as much. Turns out i only like their shoes w/ original footshape (LPs, Timp).
Altra Superior and Lone Peak are even lower stack than the Timp.
I had 3 pairs of superiors shred apart on the upper on both inside and outside just above where it connects to the base of the shoe. Same for 3 pairs of outroads. I've never had a non altra showle do this. They all died at under 250km. I have ~1800 km on a pair of nordas right now, and ~700 and 400 on a couple pairs of Topo mt5s. Ive put over 1000km on each of the last 3 pairs of topo phantoms I have had. I have a pair of timps and they have held up well, and the paradigm 4 was an amazing altra shoe. Altra is absolutely hit and miss and this topic comes up a ton. It isnt and OP thing. Its an altra thing.
Altra Lone Peak and Superior both feel wider to me than Experience
My trail running/hiking shoes that I wear for about any outdoor activity. Currently one of the recent versions of the Altra Superior. Looking at the Topo Terraventure when the Altras wear out. I liked the idea of the Altra Timp 4s because the midsoles have drainage holes, but the stack height/cushion on them is too high for my preference on rough terrain, felt unstable, they ended up being my jogging/gym shoes.
I've also done it in Altra Superiors, the first time I ever wore the v4 shoe was Kearsarge to Piute.
