Crocs Cayman are available in many colors, most of them bright and shocking. These shoes are a bit more slender than the original Crocs beach footwear, which I like because it fits a woman's foot better. I have wide feed (I often buy wide sizes), yet this are still large enough for me. The holes on the top may not be the most beautiful thing but they keep your feet cool on hot days. Also, my feet don't get as worn out from the impact of walking on hard pavement. A few complaints would be the colors (some of them are quite shocking but you can find muted ones so it's not too terrible), the fact that dirt can still get on your socks (due to the holes and open backness) and that the nubs on the inside would sometimes rub my feet a bit much. The color I bought, and which is pictured above, is teal. It is pretty bright (but not as much as some), but I think it goes well with jeans.
I wore another style of Crocs for over a week when I was on my feet constantly and while I did have some fatigue during the days, my feet felt quite refreshed in the morning. Sometimes I do trip when wearing these because the soles are so non-slip (also a good thing!). But sometimes they may catch on the floor and almost "stick" for a moment, causing a bit of a walking-stutter.
All in all, these are great shoes and can be had for some great prices online and in store sales. I would recommend checking out a pair if you can find a color you like. They do run large, so try them on before buying.
