I bought these during my Feb vacation in Florida and then wore them practically every day of the trip. I wanted a pair of beach sandals, and they were great for that, but I also wore them with capris and skirts, and found they even worked well for bike riding! They stayed on securely with the top strap behind my heel and also when I wore it in front. Very comfortable, easy on and off, and looked fantastic even on my none-too-lovely feet.
I did need to get these in a 9, while an 8 fits best with croc ballet flats. The sole is exactly the same as the Kadee and the Malindi, but in those shoes the 9 is just too big. I have wide feet and I think the straps fit me better in the 9, but my foot still fits the sole well. In shoes other than crocs I wear an 8 1/2 to 9, and often need a wide width.
So glad I found these!
