I purchased these because of all of the great reviews about the comfort of Mephisto.  First I would have to say that the air sole must be so thin it may as well not be there.  There is no arch at all.  So unless you have flat feet they are no good. the toe strap is poorly designed.  The stitching is right were it rubs the in side your toe and it is not at all smooth or soft.  Also, they do run small, I usually wear a 6.5 so I got the 37 and they just barely fit.  Would not fit a true 7. VERY DISSAPPOINTED!!!!
