Make sure that you are keeping your toenails clipped straight across and short (but not too short that your are cutting down to the quick). I fitted dance shoes on customers for 15 years and was amazed at how many girls would have these loooonggg toenails and they would wonder why their toes hurt, or toenails turned black. I couldn't stand the feel of putting on ballet or jazz shoes and have my toenails touching the end of the shoe. Just a suggestion----give it a try.[/i]
