"This is the 5.11 A/T 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 (A.T.L.A.S.) 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. Explore the 5.11 A/T Series ™ . (9/W)"
