Born in Boulder, Colorado, the BOCO AT II brings you a piece of the Colorado Mountains wherever your run takes you. The light and level 3mm drop, and multi-directional lugs, will keep you rocking out on even the rockiest of trails. While the landscape may change, the familiar Newton feeling remains the same. Rain, snow, hail and spilled coffee are no match for the durable all-weather upper. It is time to take your Newtons over the river and through the woods.

Awesome shoe. I have really liked the Terra Momentums, then the BOCOs and now the BOCO AT II. These are the most comfortable Newtons of the three.

New to Newton
Replaced my Altra Lone Peak 2 with these trail shoes. Much better fit around my toes compared to the lone peak. These feel custom made for my feet. Not much lacing adjustment needed to get comfortable. These will be trail training shoes primarily (Fate 2 for road work). Grip is fine up and down hills as well as traction on damp rocks and roots. Impression is great so far. Bottom line: If I don't have to think about my feet then the shoes are doing their job. 40 miles so far.
