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.

Why are these not available in 12.5 size?

Asked by: ozzymunky
In my experience in outdoor retail...a good chunk being at's rare to find men's shoes in half sizes above 12. LaSportiva is an exception given their Euro sizing. Most American brands do not go halfsies above 12.
