Bought several pair of different Colibri boots and I think that these are my favorite version of the bunch. For some reason a 38 fits well in this style, while I need a 39 in the others. I take a 7.5 US size in most shoes. Comfortable considering the higher than I usually like heel. I love El Naturalista shoes and boots, but find that you may need to go up a size for length or width in the toes box in some styles. Cannot beat Amazon prices on these boots! Paid much more earlier in the year for another similar pair from another site.
