My husband has some reef sandals and I've worn them on occasion and found them to be comfortable. I ordered a pair when I started swimming. These are of good quality, but they are not half as comfortable as those my husband owns. The strap on these is strangely placed, further than I'd like from the toe portion, leaving a lot of foam around your toes (is this for toe stubbing protection?), and it is not comfortable for me at all. As I wear these a total of twenty minutes per wear it is fine. Husband has now informed me (he's a flip flop lover, I never wear them) that I have to try many on before I find my perfect fit. So, if you have narrow/medium feet and longish toes, you might have just found your slipper, Cinderella. If you, like me, have wide feet, average toes, and wear a 9.5, these might not work for you.
