The latest athletic work sneakers are so lightweight and comfortable 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 mesh with reinforcements in high-abrasion areas. We added composite safety toes, electrical hazard protection, Thermoplastic Polyurethane heel clips to enhance stability, and the Anti-Fatigue Technology footbeds that provide shock absorption and energy return for long periods on your feet. Remaining true to these commitments, their breathable, moisture-wicking linings are made of ReBOTL material containing at least 50% recycled plastic.
