I have a wide foot and it is difficult to find shoes that fit without special ordering (and 6.5W is not readily available regardless).  These in a 7 (sized up for running shoes to account for swelling) fit beautifully, with plenty of room in the toe box for my wide feet.  I also have a very high arch and some knee problems, and these feel great when I run.  Doing the runner's box lace also gave plenty of room for my high instep, and eliminated the terrible pain I used to experience from running shoes laced tightly enough not to slip.  I've been able to really up my mileage this season without any of the lingering aches and pains, particularly in my feet and shins, that I had in the past.  I happened to be in my PT's office shortly after I got them and she reviewed my gait running at my current top speed; she said these shoes are worth every penny because they're doing a great job controlling my gait and therefore helping prevent injury.  One caveat that irks me... I've bought two pairs so far, because they really are the most ideal running shoes I've ever worn (for me, obviously YMMV). In the first pair, a slight flaw in the stitching of the left shoe at the top of the curved heel cutout created a lump just under the fabric that gave me a constant blister. I actually had to cut the fabric and snip out the little lump, which I was loathe to do in newer shoes that cost a small fortune.  When I bought the second pair, it had the same problem, but in the right shoe.  Considering these go for nearly $150 (depending on where you source them), I am annoyed that this is apparently a manufacturing issue and I can't trust that I can buy a pair that won't cause blisters.  I ran the Chicago Triathlon this weekend with an unhealed, uncomfortable blister because of it.  It makes me feel like the only options for buying these are to pay way more in a store so you can test run them on site and check for the stitching flaw, or order them more affordably online but know you may haveto return multiple times if the flaw is present. They work so well in every other regard that I'll probably continue to buy them. This brand has always been my savior in terms of width, I'll just hope they fix this issue in future iterations.
