text: I'll second what another reviewer said - the thong is placed too far back. The walking surface of my heel just barely rests on the insole, while there is easily 3/4&#34; in front of my toes. In fact, where my heel curves back and up, it overhangs the sole. Probably not great to drive in.<br /><br />Still, they're pretty comfortable and inexpensive, and I'm not planning on running a marathon in them.
