Why are they so cool? Well they're eco-friendly, the soles are made with recycled car tire tubes and designed with longevity and style in mind. Hard to find these days with fashions turning over so quickly to have something made to last, and in a pair of flats, that's just what I would be looking for. Loving the aqua blue color as well! I found them here at Extraseed's Etsy shop. I'd love to get a pair, although the largest size they sell is a 9, boo for my big fat large size 10 feet. They are still amazing to look at!
