The foam insole is removeable which means that you can get a custom fit by replacing the insole (or add arch support, orthotics, etc.) or just wear them as is.
ABOUT SUEDE SOLES:
These are made with Suede Soles which are wonderful to dance on but require occasional upkeep (it's usually a problem with catching the edge on a piece of hardwood that is sticking up on the dance floor).
If you need to re-glue the suede many people just use crazy glue gel. We have also found that commercially produced shoe repair glue (available from the shoe repair shop in your local mall) works great.
You're not supposed to wear suede soles outside - but every swing dancer knows that you can make suede soles faster by wearing them everywhere to get them dirty, then dance in them until they're shiny on the bottom.
If you prefer them less zippy you can dull the "mirror finish" they can get by roughing them up with a wire brush periodically. Just remember that when they get wet in the rain they won't spin very easily (conversely - if they're too slippery just spill your drink on the floor and step in it!).
Our test group said that these fit a half size off and almost all went down one half size - so if you fit two sizes, it's best to go with the smaller of the two (say, if you fit 6.5 to 7; you will most likely fit the 6.5 best).
For Men: If you wear 13.5 or smaller you can easily wear these. Just add 1.5 to your men's size and that's the size you should fit (i.e.: men's size 10 + 1.5 = size / women's 11.5 in this style).
