517 aka Aviator Boots, are no-nonsense unisex ankle boots made of water-repellent leather that are suitable for wearing everywhere, in the city and the woods, and any weather. They are manufactured in Europe by the same factory making one of the most legendary military boots, M77s. The same manufacturer has also worked with well-known brands, including Dr. Martens and Rossignol. So we assure you they last longer and are of better quality than similar, more expensive fashion boots in your local shoe stores. As Aviators have no lining besides genuine leather, we recommend wearing warmer socks in freezing weather. Black Aviators are the go-to boots of Annamari, one of the founders of whatshoes.  Upper: Water-repellent genuine leather Outsole: Direct-injected PU Lining: Leather, no extra lining Insole: Anatomical, antibacterial and washable Weight: 1,2 kg (size 41) Made in: Estonia, Europe
