I purchased these shoes because I have Crocs flip-flops that I love.  But these Crocs didn't work.  The canvas is hard and the inside-seam rubbed the top-side of my foot.  I wear a 7 1/2 and I got an 8 which seemed more like a 7.  My heal was in the perfect place, so they were not too small.  My big toe (which is really not that big) rubbed on the inside of the shoe really bad because the canvas was not positioned on the sole right and it pushed my foot sideways. The fit was REALLY bad. I agree with the other reviewer that these shoes should be tried on before purchasing because the fit is odd.
