I don't know what it is about these shoes, but after wearing them for about 2 days, my feet felt like they were on fire.  I almost went to the doctor thinking I had a problem developing, until I realized the problem had developed since I'd worn the new shoes- went back to my old shoes, and my feet are almost back to normal (it's take about 2 days).  I think it's the way the tongue is placed, or maybe it is a combination of the slant of the bed of the shoe and the tongue, because if I loosened the laces completely (And didn't tie them), it got a little better- though not completely better.  I'm sure these shoes are fine for people with normal feet, but if you have any special health problems, be aware that these are not the equivalent of a New Balance shoe (for example).  My orthopedic surgeon recommended New Balance, and I've been wearing those for 9 years, but I'm a little tired of them- and I wanted something different.  Alas, this won't be it.  It's a really sharp looking shoe, but for whatever reason, even with my custom orthotics, I could not wear it.  Just wanted to give a heads up to you out there, if you have some existing problems with your feet- be careful with these shoes.
