I ordered a size up from my usual size as other reviewers warned that they fit small.  I found the shoe to have no arch support, and they felt very wide even with a thick sock.  I tried to dance in these shoes, and it felt as though I was wearing the box the shoe came in because the shoe was so large and I felt clumsy in them.  There is a huge amount of padding in the shoe, so that is why they warn you to order a size up.  They may be o.k. for a zumba class, but they were horrible for ballroom practice shoes.  I returned them.
