This is my sixth pair of El Naturalista footwear, and my first from their boot collection. I grow increasingly impressed with the unique styling, all natural materials, craftsmanship, and fit. I wear a 7.5B or 37.5B in European sizing, so in this line the size 38 is perfect. Just enough wiggle room for toes and perhaps a pair of socks. I would recommend anyone who wears a half-size to size up to the next round number (e.g. a size 6.5 should order a 37). This low-cut bootie is comfortable around the ankle, too - does not cut in like some other booties I've tried. Much more stylish on the foot than it might appear in the photos - will look great with jeans or leggings. Highly recommended.
