Why does Vionic not have the same arch support across all their products? These flats (and their kitten heels too) are nothing like their Jura slide sandals. These flats have really low arch support - might work for people with really flat feet, but if you have tall arches, steer clear and head for the Vionic Jura slide sandals. Those have the best arch support for tall arches that I've ever found. These flats were also slightly large - wish Vionic make half sizes for small feet (they don't make 5.5 in women's - it jumps from 5 to 6), and had extremely stiff soles (which made them kind of hard to walk in). Returned.
