I've only had them a couple weeks, but love them.  I ordered in both 8.5 and 9.  I WISH they came in an 8.5 wide.  The 8.5 is a little tight on the ball of my foot, but fits lengthwise and my arch.  the 9 fits the ball, but is too long.  I kept both.  I stretched out the 8.5 a little (won't stretch much because of stitching), and so far it's working.  I agree with other reviews that say they're comfy and supportive.  I have plantar faciitis, so I usually can't wear sandals.  I've worn these walking for 2-3 mile walks, and no foot pain at all.  Will definitely buy again.
