Just got my Reefs today...On Sunday believe it or not. They started Sunday delivery out here in the sticks of central Illinois. GO AMAZON !!!<br /><br />These sandals are very comfortable and decently priced. It is always a gamble buying shoes or sandals-flip-flops online. I wear a 10 1/2 and ordered an 11. They fit perfectly with no room to spare. If I were to order them again I would order an 11 1/2. The heel of my foot does not overhang the sandal but it is very close. I would say my heel is exactly even with the back of the sandal. I wear a wide shoe more because of aged joints than necessarily a wide foot. There is no room to spare on the width either. I did not see any way to order a wider flip-flop from them though. The arch support seems very good and they were comfortable the first time I put them on. Initially they did not seem to be very grippy.  They were kind of slippery on my linoleum floor. but after an hour or so of wearing them they started to grip the ground better. They are very lightweight, look good, and appear to be well made. All in all I would buy them again. Just note that you must order a full size bigger than your normal size, and they probably will not fit a person with a wide foot.
