Get ready for summer with the Butts and Shoulders sandals. A durable, lightweight EVA outsole with an extra comfortable memory foam midsole. The entire upper material is made of vegetable-tanned leather and is hand-sewn. Extremely durable and like all Butts and Shoulders natural leather products, these sandals will develop their own personal patina over time. Due to the lack of heavy metals during tanning, the leather gets a very nice patina from the UV rays and turns golden brown. This process can be accelerated by oiling the leather.
