Superior Series

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 :)

Altra superior 5, can handle everything above, in cold cold with warm socks is okay, but its breezy on the top part.

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

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 is my go to because of low stack and ground feel. . Lone peak GTX my winter/early spring shoe.

Altra Superior and Lone Peak are even lower stack than the Timp.
