From Skippy Blair:
Hold onto the back of a chair, the kitchen sink, or whatever - just for stability and balance. Now spread your toes wide apart - as if you were trying to make a shoe tree out of your foot. (If you are so inclined - go ahead and take your shoes off so that you can SEE the difference.) Press all three toes (Big one & next two) down into the floor. If you stay in place, and don't buckle your knees, this action should push your body upward. Now use that same pressure into the floor and send your body to the SIDE - or BACK - or FORWARD - instead of UP! The same pressure that moved you UP - can move you OUT!
Some people find it physically difficult to stretch their toes - particularly if this has not been part of their daily routine. However, stretching the toes is a vital, necessary practice, if you want to have strong, healthy feet. Stretching the toes takes pressure off of bunions. - And if you DON'T have bunions, stretching the toes will serve as a form of prevention. Stretching the toes allows the arch to settle into the floor and redistributes your weight. Ladies have reported dancing all night without discomfort, once they learned to spread their toes, inside their shoe, instead of scrunching the toes together.
Many dancers "work out" to keep their bodies in shape. Feet also need a "work out": Press yourself up onto your "3-Toe Base" - Stretch the toes as wide apart as they will go. Move your body up and down through the flexibility and control of your ankles - (not the knees) Repeating this exercise can become a good "workout" for the feet. In a few short weeks you will enjoy more flexibility and strength in your toes. Your dancing will improve and your feet will feel wonderful!
If you want to know what the "3-toe Base" is, let me know, I'll copy and paste it for you. It'll change your dancing.
