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.

Best yet
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.

Great for Cross Training
I wear the Newtown Gravity V for running and was looking for a good cross training shoe. I found exactly what I was looking for in BOCA AT II shoe. They are light, but have a strong flat rubber bottom. I'm sure that is the design for trail running shoes, and it works well for cross training stability/support. The 13 runs true to size. I started using the top notch for the laces this week and it improved stability even better. I would highly recommend this shoes to someone who is looking for an overall solid cross training shoe.

Stable, no slip and great grip
Completed my Spartan Trifecta in these shoes, all around the SE US. Comfortable fit, expanded toe box to let your toes splay, solid heal cup and depth to feel secure even through swamp running. I always knew where my feet were despite them being covered in mud or water soaked. Great traction on all terrain, shale inclines, shale declines, climbing wood walls, and over gravel. Looking for a capable and comfortable shoe, this is the one!

Excellent trail shoe.
Just completed 66k over a few trail runs and find them excellent. The fit is perfect I have had problems in the past but with the Boco AT II there is plenty room for the toes to spread out.
Wet grass today was no problem, up and down. Gravel fire trails no bother mud and snow they are at home. Ok wet roots and ice avoid, but unless you go with spikes it,s the same for all.
Great shoe for the fine Scottish winter weather.

Trail Beast
I was really hesitant to order these after watching the Ginger Runner's review of the first model. But AT II is a big improvement from what Ethan Newberry had described in the first AT. These are rugged, giving me confidence on the trail and going fast. I am really particular about keeping my trail shoes on the trail and my road shoes on the road and these are no exception. Newton's forefoot style with its lugs are more noticeable on the trail and definitely a Newton shoe on the trail. But when I run to the trail from my house or cross the road to get to the rest of the trail, I don't enjoy the ride, though I'm getting used to it. But that's not the point of a trail shoe and it's bearable for the short amount of time I am on the road in these.

A great shoe for softer trails.
The Boco AT II is a different kind of Newton. It's relatively stiff, the midsole is firm and it doesn't have the forefoot pop of road Newtons. But it is an excellent shoe for softer trails where the stiffness and firmness help stability. The outsole with its outer lugs is also very stable and plenty grippy on woodland trails that I run on. I can't comment on scree or other rockier surfaces. It is by far and away the best trail shoe I've run in. Too stiff and firm to be a great shoe on pavement though.
