This is the 5.11 A.T.L.A.S. Mid. That's mid-height, not mid-night, though it will find favor on that shift to be sure. Featuring 3D molded TPR toe and heel protection, a welded/mesh upper, and high performance, high traction outsole, the All Terrain Load Assistance System will mitigate the rigors of a heavy load bearing job (and in no small way, either). The mids were developed to work with your work weight. Work longer, with less stress even when you're loaded down.
