Vivo barefoot MAGNA TRAIL II FG WOMENS, size 40 or 8.5 / 9 US

Vivo barefoot MAGNA TRAIL II FG WOMENS, size 40 - fits about an 8.5/9. Love them and look cute on but they don't work for me. They've been worn about 3-4 times by me (max hike was 3 miles) but I bought them used although I don't think they used them much either. Worn in garden of the gods, hence the red dirt on the top but I'm sure that would come out easily. Otherwise, great condition!
