Born in Boulder, Colorado, the BOCO AT 4 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.
