The Sentry 2020 line by Terra is as tough as they come, with combat boot styling that hints at the fortress inside: a full-length internal XRD metatarsal guard. The lightweight, shock-absorbing midsole and premium PU FOOTBED work together to maximize all-day comfort. The full-grain waterproof brown leather is seam sealed, so the elements don't stand a chance. Finishing the job, a composite KRYPTOE safety toe and composite plate combine with the TecTuff leather back panel and heavy-duty TPU outsole for safety, abrasion resistance and traction like never before. Meeting ASTM and CSA Grade 1 standards, the Sentry 2020 work boots have the qualifications needed for safety footwear in a variety of environments.
