I chose the Graphite color that is a pretty dark gray (too bright). My height is 37, 5 and I took the shoe size 37-38 (M5 -W7). It'll just length (knock a little) so if you do the 38, take big PLUS! But I really floats in width my foot walk (I walk the fine). In short, over my foot shape that is not the perfect shoes ... it will go inside without moving because it is still very comfortable, small spikes are a delight to the foot. It is soft (made in Italy, not in China, and apparently it's better). With thick socks, it will serve me slippers (good but it's not really stylish !! ;-) I regret that the shape of each model is not better described, because there was perhaps a more appropriate model for feet. So if you have the good wide base and top of the foot rather high, or swollen feet, swollen ... these shoes will suit you perfectly. Last thing: they are super light to carry. Precision: I hoped to change them, but stupidly I cut the label (it bothered me to try), so do not cut off the label because I read on the site to return the label must be attached. EDIT: I found a solution for a bit short waist: I pulled the strap on each side of Crocs logo on the back, and it worked well relaxed, my toes are off the bottom - )) so it is much better ... and what a delight these small spikes for feet. Kudos to Amazon for the unbeatable price and fast delivery.
