These shoes are comfortable for the most part, HOWEVER, the right shoe's thong made a sore (almost like a small hole) on my foot. Because I read the shoes were really comfortable, I bought them for a trip. I only brought the fit-flops and a pair of tennis shoes for walking shoes with me on the trip. After a day of wearing the FitFlops, I had a blister/sore between my toes where the thong is.  It was so deep that I had to walk with a slight limp. Because I needed to wear them, I had to wear a band-aid where the sore was or wear a band-aid around the thong part. It was the stitching on the thong that created the sore. Needless to say, I did not have good experience with these shoes.  I feel like I can't return them because I wore them. I will not be purchasing another pair of FitFlops.
