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.

Great Shoe, but needs an update
I've owned 5 pairs of Newton's; Gravity III/IV/V, Distance IV, and BOCO AT, and generally love the shoes! The Boco AT are a great shoe; more than enough protection, cushioning, and traction for most trails, unless you're in seriously wet/muddy terrain. My only real gripe with the shoe, is that I find it to be too rigid, especially in comparison to the Gravity line of shoes. Granted, I like my shoes as flexible as possible, so I would love to see a "trail version" of the MV3, but I'm an exception to the norm. When can we expect an update of this shoe with more flexibility?

Trail Stompers
Love these. My second pair. Great for everything from soft muddy trails to technical mountain single track. Hands down my favorite pair of trail shoes.

My new "all rounders"
I've run about 50 mile in the BOCO AT II and they are my new go to "all rounders". We have heavy mud/crud out here in the New Mexican desert in winter and I havnt had wet feet or cold toes yet! They charge through it and with a hose off when I get home they are good to wear to the gym the next morning! It's a trail shoe with all the perks of race shoe. It's fast and comfortable and appears to be very well made. Can't wait to put another big block of miles in using the BOCO AT II.

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.
