These are a sandal version from Simple shoes. They are constructed from materials like: jute, bamboo (linings), cotton, natural latex, and recycled tires. They look comfy!

Simple is a relatively new shoe company that is going after the eco friendly crowd in a BIG way. However, I like their shoes and they are doing a good thing …so bring ‘em on down!! This MaryJane styled flat has a nubby burlap-y texture with a cute funky style. The outsole is a recycled tire and the glues are water based and less toxic.
