Make Your Own Dance Shoes - cheaply!
For about $25, grab a pair of comfy gym shoes, flats, sandals, etc from local department store (KMart, WalMart). Look for the shoes that have a flat sole or no tread. Not the bumpy grippy bottoms for traction.
OPTION 1 - QUCIK FIX - ADHESIVE FELT
For a quick fix, but not permanent. You can purchase a large piece of felt or adhesive felt from any arts & crafts stores. It's a layer of felt and an adhesive backing. You can match the felt to your shoe colors too. So all you do is slap it to your shoe and DONE! It will be VERY slick, so you may want to keep your heel grippy. Practice a few times before heading out on the dance floor. It may not stay permanently on your shoe, but a good quick fix.
OPTION 2 - SUEDE / LEATHER / FELT
More labor, but longer-lasting. You can make two different types of shoes: INDOOR and OUTDOOR. Since some dance events are indoors (wood-marble-tile) and outdoor (concrete/brick/sticky).
then - Either one, you'll need a tube of "Shoe Goo" or similar clear adhesive that bonds to rubber, plastic, leather, fabric, etc. This is probably also located in the shoe depart or at your local hardware store.
INDOOR SHOES: buy a piece of THICK leather/suede or even heavy-duty felt. These can be found at your arts-n-craft stores. Be sure to find one piece of fabric that will fit the entire shoe you want to cover. Remember, sometimes you only need to cover the ball of the foot area, not always the entire shoe leaving the heel for grip.
OUTDOOR SHOES: since most outdoor venue's floors may be concrete, brick, or grass, - you may want something that can stand up to a larger wear-n-tear. You can just find a sandle, gym shoe, or something with littel tread as possible.
CUSTOM OUTDOOR - Cut out a piece of plastic off any square/flat containers (like kitty litter or detergent buckets) that will fit the entire front section of the shoe. Glue the plastic piece put on the ball of thoe shoe. You can also cut the plastic in two pieces (left-to-right) so you the shoe can bend when just walking on it. If you dance to a lot of outdoor events, you can do this to comfy sandals too. (submitted from David F in NC for this idea)
TIP: You'll want to measure out the fabric/plastic pieces bigger than shoes, glue them on, and then trim to fit AFTER the glue sets.
