I have a couple hundred miles on this pair at most now.  The inside of the heel of one of the shoes has worn through and today I got a large blister about three miles from home and had a totally bloody sock by the time I got home.  I've been wearing Gel Kayanos since about version 11` or 13 and they always fit the same, very comfortable but with good support.  So I guess they decided to change a good thing  and stuff them with padding so only the most narrow foot will fit comfortably.  I suppose there is a wider version but good luck trying to find anything but a regular fit at a local store and I'm not risk $150 over the internet hoping they'll fit.  Final gripe: the laces are about 4-6 inches too short now for back lacing.  It is hard getting them on and off without totally undoing the back lacing.  Big disappointment.  Follow up: The heel padding broke out of the right shoe.  If I don't wear a  band aid for my 5-6 mile run I come home with the back half of my non cotton sock soaked in blood.
