I love these shoes so ridiculously much that I bought a pair in every color. I have a terrible time finding shoes that fit - I wear size 5 1/2 and I have high arches, and an aversion to shoes with soles that aren't flexible. These are a win all around - true to size and available in sizes smaller than 6; they don't cut into the top of my foot, and they are so flexible it's almost like being barefoot. I've never tried Clarks shoes before but they will definitely be my first choice in the future!
