Renowned 5.11 Tactical boot steps up its profile with heightened performance and comfort. The A.T.A.C. 2.0 8" Shield lightens things up but remains deadly serious about delivering superior safety in the most unforgiving environments. An added 5.11 SlipStream™ waterproof / bloodborne pathogen membrane, ASTM/CSA CARBON-TAC toe, and an ASTM/CSA puncture resistant board provide critical protection. Full-length dual durometer Ortholite® footbed works to keep your feet cool, dry, and comfortable all day every day. Another addition, the Achilles heel flex zone, gives a critical part of your foot more range of motion without compromising support and stability. This boot is so tough, it can live up to the ASTM 2413-17 M I/75 C/75 EH PR standards, day in and day out. CSA Z195-09 rated for compression, cutting, abrasion, and electrical discharge protection.
