I got these shoes because I have to be on my feet to teach for about 4 hours at a time.  I was really excited after the 1st time I wore them because I didn't have any cramps in my feet or back pain at the end of the day!  I haven't experienced any tugging or rubbing with these either.  As for the fit, I normally wear a 6.5-7 and the 37 fit just fine.  One last note, I ordered the chocolate color and it was just a bit lighter than it looks online.  These are great shoes and I wear them all day with zero problems.
