The 5.11 A/T 8” ARID is a performance boot built from the sole up to increase performance. The All Terrain Load Assistance System (A.T.L.A.S.) is a force multiplier for those who carry heavy weight on long shifts. The boots were developed to work with your "work weight". This boot is constructed of nylon for high abrasion and a durable suede upper. Additional features include a YKK® side zipper and a locking ankle eyelet, and a high traction outsole so you can take those corners in a foot pursuit or run headlong into whatever challenge you’re up against.
