I chose these because of the height and hope of ankle support  -and cute, distinctive looks, and the appearance of being well made.  I am one of those women who can fall off of my clogs or mules and go tumbling.  These actually provide ankle support, and they are extremely cute. I purchased them in 2 colors right off - the one with pink and optical, which looks white.  I put them on for the first time my way to work, and was  comfortable all day long!!!  I was wearing socks.  I wore the second pair around the house when I got home, then ordered a pair with blue.  My true foot size  is 9.5 N - and Euro 40 is the correct size. 41 would be much too big, and 39 too smal.. I may have to put inserts in to make them more narrow once I am not wearing socks.  They arrived beautifully packed, with their own  shoe bag.  The zippers work great,  and the fit for my ankle really great. There is no tightening or loosening, so either the ankles fit or they don't. Vaquero is much  lighter than it looks in the photo-a medium blue  like denim and a  nice leaf green. and I think that they are much prettier this way.....now on my third pair within a couple of weeks and have ordered a fourth!  I wore them with Unmatched Sole Mates socks from Amazon, which are the cutest socks I have ever owned!!
