Type Z - Sergio (Dark Brown) - Men's: Please note: due to the tanning process, there may be a non-harmful white powder on the upper; it is easily wiped off and does not affect the shoe in any way. Rugged, motorcycle-inspired boot. Distressed leather upper to give it a pre-worn, open road look. Zip closure down the side. Padded footbed. Durable outsole with rubber tread.
