This is the third pair of these shoes (although different colors)  I've ordered. I'd read the reviews about the oddness in sizing, but decided to go ahead because the shoe itself is so flexible (to accommodate my plantar fasciitis problem) and fit could be minimally altered with inserts or foot petals. The pair in black fit fine without inserts, the navy blue pair needed heel inserts only, and this polka dot pair needed both heel and a  foot insert. That said-- because of the heel height-- they are such a comfortable shoe to wear, that it's worth messing with the inserts to wear them!
