Timberland Pro Morphix 6″ Inch Waterproof Composite Toe Work Boot TB0A63YKEIU. The next generation of athletic work boots has arrived—offering more than just modern style. Timberland PRO Morphix delivers agility, lightweight performance, full ankle support, and flexibility. Its metal- and mutilation-free uppers are crafted from abrasion-resistant coated leather, ripstop nylon, and TPU reinforcements to keep them lightweight. They also feature internal waterproof membranes designed to provide protection against water and blood-borne pathogens. Key safety and performance elements include composite safety toes, electrical hazard protection, and Timberland PRO FLEX Technology outsoles, built with anatomically placed flex grooves in heat-, oil-, slip-, and abrasion-resistant, non-marking rubber with deep lugs for enhanced traction. Lightweight Hover Spring foam midsoles add comfort, durability, and flexibility, while Anti-Fatigue Technology footbeds help absorb shock and return energy. Breathable, moisture-wicking linings made with ReBOTL fabric—containing at least 50% recycled PET plastic—are treated with Microban for odor control.
