Timberland Authentics 3-Eye Boat Shoes. In 1978, Timberland took premium leathers, used hand-stitching, and crafted 3-eye boat shoe uppers that we combined with our rugged boot lug outsole. It was at that moment, the 3-Eye Lug Handsewn boat shoe was born. Upper made with Premium Timberland® Leather. 360° functional lacing system. Leather lining. 3/4-length leather-lined footbed. Traditional handsewn construction. Rubber outsole. Imported.
