Dance shoes are generally worn smaller than you would wear your regular street shoes.
They must fit snugly without hurting so you maintain proper balance on the dance floor.
This means that all parts of the shoes should be covered by your feet.
If your feet move easily inside the shoes, you cannot properly control your balance or your
dance posture. In closed-toe styles (ladies and mens), the toes should be as close to the
end of the shoes as is possible without actually rubbing. In the sandals, the toes should
completely cover the soles of the shoes and it is preferable if the toes actually
"hang over the edges" of the shoes just a bit (up to 1/4 inch). When the shoes begin
to stretch enough to allow your feet to slip inside them, invest in a pair of foam inner
soles and use them. The more your feet can move inside dance shoes, the faster the shoes
will stretch, become misshapen and wear out.
