I like Altra. I like the wide toe box. I wish they were a little more high volume, too. I need very wide shoes in part because I have a high arch and a high volume foot. I have had a few pairs, and some models have fit me better than others, like anyone's shoes.

They seem about as sturdy as any nylon and poly foam shoe that is basically all glued together. That is, they are moderately long lasting at best. You don't get light and sturdy in the same shoe.

I have not tried Altria, but I have a pair of Lems that are shockingly comfortable and shoe like for a wide toe box zero drop minimalist shoe. I have the Primal 2, but they have several models.
