I've have Therashoe sandals which are no longer available, and have had Champion sandals, a cheaper version of the Therashoe, also no longer available, both very similar to the FitFlop. The Therashoe sandals are still in great condition, even after wearing them almost exclusively from April thru November for 4 years ( live in Texas where it's warm). The Champion sandals (a cheaper version of the Therashoe and FitFlop) that I had in black finally broke last summer after two years so I ordered the FitFlop in black to give them a try and they are so amazingly comfortable. More comfortable than Champions and about the same as the Therashoe sandals. These are sturdy and look fantastic. I absolutely love them, and if I had lots of money, I'd order enough pairs to last me the rest of my life. I will be ordering more in black and different colors. As far as size I'm usually a size 7- 71/2 in open toed shoes, and the size 7 fits me perfectly. I'd say the sizing is slightly generous, bigger rather than smaller, but not by much. Pretty close to true. Highly recommend these and I hope FitPlops will always be available.
