I thought these would be comfortable since they are made by Clarks, however they caused blisters and tore up the back of my foot. There is built in padding on the back part of the shoe which was fairly stiff and caused the irritation.<br />I am usually in between a 6.5/7 and went with a 7, so there was a little wiggle room (which is what I wanted, did not want my feet stuffed into them.) I cannot wear them for more than one hour before having a blister form. And unfortunately I cannot return them.
