These shoes are lovely and comfortable.  Initially, I got a 5m but found them narrow and slightly small.  I was able to quickly get the next size up and was all set before my competition.  The fit was perfect, and they are made in the USA.  At no time did I feel my feet constrained and I was able to go from smooth dances to rhythm and Latin styles without a hitch.  I at no point had to remove them.  I had them on for more than 4 hours.  The vendor was able to make the switch quickly without a fuss.  I will, I am sure, wear them out before I tire of them.  Well worth it.
