Boots are so lightweight and comfortable that you might forget they offer safety and durability features as well. Utilizing Timberland PRO® FLEX technology, durable stretch fabrics are incorporated with thick, ultra-comfortable, injection-molded EVA outsoles that have anatomically positioned flex grooves so you get full range of motion without resistance. The Setra’s metal- and mutilation-free uppers consist of breathable, durable polyester mesh with reinforcements in high-abrasion areas. Also has composite safety toes, electrical hazard protection, TPU heel clips to enhance stability, and Anti-Fatigue Technology footbeds that provide shock absorption and energy return for long periods on your feet. Their breathable, moisture-wicking linings are made of ReBOTL™ fabric containing at least 50% recycled plastic with an antimicrobial treatment for odor control. Ships fast!!!!
