I'm a diehard El Naturalista fan . . . bought this shoe in two colors. When I first tried it on, it seemed a half-size too large. But the magic of EN is that the Velcro-attached strap anchors the shoe to the foot so firmly that a small size discrepancy virtually disappears. I'm also thinking that in the summer, when feet tend to swell, I'll be happy to have these shoes. Other positive features: made in Spain, 'green' manufacture.
