Inspired by our original waterproof boot, this all-season style gives you tireless waterproof performance and instantly recognizable work-boot styling. Other essential features include 200 grams of warm, down-free PrimaLoft® insulation, a padded collar for a comfortable fit around the ankle and a rubber lug outsole for traction. A comfort system, adopted from Timberland PRO, designed with shock-absorbing, geometrical technology that returns energy back to the foot to deliver all-day support and comfort. PrimaLoft® insulation is a soft, lightweight compressible down alternative insulation. It uses a patented microfiber structure to help retain warmth, even if the fibers get wet - helping you stay dry, warm and comfortable. By purchasing this product, you are supporting Leather Working Group certified tanneries https://www.leatherworkinggroup.com/ Our waterproof footwear incorporates a variety of advanced waterproofing materials, treatments and processes. We start with waterproof leathers that are sealed as part of the tanning process; we then either seam-seal the footwear or use an internal waterproof breathable membrane to help feet stay dry. Tongues and zippers treated with durable water resistant coatings utilize integrated gussets, to further deter water entry.
