I have about 5 pairs of tennis shoes, all the same size.  I rotate them daily because I work long 16 hour shifts working on concrete floors.  These shoes are way too narrow and small that my feet went numb on my drive to work.  I will send back and go 1/2 size up and hope this helps.  I did not even get to wear at work.  If you try these go up a half size at least.
