Vivo Barefoot primus trail runners or casual lightweight hiking shoe. In excellent condition and only worn a few times. Cute black / olive green colors. Women’s EU size 40, or a U.S. 8.5-9. I am pretty true to a 9 and these fit great - I think they could work for 8.5 too, but I wouldn’t recommend for someone on the larger 9-9.5 end of spectrum. I was a little nervous about the large grippy sole and if it would feel “bumpy” from a barefooted shoe perspective but it doesn’t and they have a smooth step! Brand new insoles and extra laces for this shoe included in purchase.
