Simple goes to great lengths to make the Women's Carnival Leather Shoe as eco-friendly as possible. From the recycled PET of the laces to the organic cotton lining and eco-certified leather upper, you can rest assured that every effort was made to reduce this shoe's footprint. Best of all, the outsole is made directly from a recycled car tire. Combined with the hip, casual vibe this shoe exudes with every step, and its extreme comfort and durability, the Carnival adds up to a shoe that deserves some serious consideration.
