The original Timberland waterproof "yellow" boot was built in 1973. It wasn't long before kids' styles were added to the line. These boots for kids are ready for adventure with uppers made with waterproof Premium Timberland Leather, a ReBOTL™ fabric lining containing at least 50% recycled plastic, and non-marking rubber soles. Plus, an EVA footbed and steel shank for arch support up the comfort.
