I was SO SO happy to find these shoes in a wider size.  I've normally always worn an 8.5 B in ASICS, but lately it seems that the ASICS I've tried have been more narrow than usual.  My foot hasn't changed in size and a few of my other friends have noticed it, too.  I decided to try the 8.5 D (which is harder to find) and they fit almost perfectly.  I like them so much that I ordered a second pair as a back up!
