The A.T.A.C. 2.0 6" 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 resistant 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 F2413-17 I/75/C75 EH PR standards, day in and day out. CSA Z195-09 rated for protection. Imported.
