FYI: These are made from recycled bottles!

Promising review: “I bought these shoes to wear on vacation to the Grand Canyon. I did a lot of walking on that trip, and my feet never hurt, and I still looked cute. Then, a few months later, we went to Durango, Colorado and did a ton of walking, and again, my feet never hurt. I washed them and let them air dry several times over the next year, and they came out great every time. They soon became my daily shoes to wear around the house. I have already bought a second pair to replace them so I can still look cute and be comfortable and wear the first pair when I water the garden. I would definitely recommend these shoes!” —J. Perkins
