I don't wear heels often & have a hard to fit foot (size 5 narrow - search for that one & let me know if you find anything other than sneakers).  I wore these to a wedding & not only wore them all day, since it was a center city wedding & reception, I walked several blocks from parking garage to chruch, around town to reception, back to garage, etc.& not issues with rubbing.  I wish I could wear these to work because I alway end up wearing flats & old lady shoes to work.
