Like Birkentstocks, but fancier, these incredibly durable, Spanish-made sandals will last for many years. They're super comfortable and brand new, never worn. Their website says, "Bio line with platform, sport-technical yet natural style. With a 100% natural eva rubber midsole, guaranteeing flexibility and comfort in your everyday life." Upper is calf leather with working metal buckles. Made by The Art Company, also known as El Naturalista.
