Rated 5 out of 5 by from Trail runners dream shoe If you are a fan of zero drop and not a lot of cushion, these should be your go to trail runners. They are the best I've ever ran in for trails in the Northwest that can be muddy and extremely uneven rocky surfaces. Love them and so do my feet and legs.

Why are these not available in 12.5 size?

Asked by: ozzymunky
I have Altras in 12.5 US and about 6 pairs of Hoka One One in 12.5US as well. Never had a problem with finding them

Do these help with over pronation? Or is there an insole available? If not which Altra trail runners are good for correcting over pronation 

Asked by: Troutslayer414
​This shoe is a neutral shoe. Altra makes a few road running shoes for minimal pronation such as the Provision 2.5.
