I find it's difficult to size-guess Naturalizer (and other brands), so I downloaded and printed the size chart from their website and &#34;measure-guessed&#34; at home. The length and narrow width are perfect, and I really like the two Velcro-adjustments that are possible for the width. This will be handy when my feet react to hot weather and/or too much sandal-walking. I am used to sneaker life for daily running around, so the harder sole will take getting used to. I think the slight heel wedge will make these more comfortable over the long run. Very happy with the purchase. Only 4 stars because I haven't worn them for an extended length of time. Sandal feet, happy feet, purr purr purr.
