The Junior Timberland® Premium 6-Inch Waterproof Boot is crafted to help keep growing feet warm and comfortable. It features an EVA footbed, 200 grams of PrimaLoft® insulation, and a padded leather collar. It's made with durable Premium Timberland® leather and a ReBOTL™ fabric lining containing at least 50% recycled PET plastic. 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.
