Why learn Salsa shines/footwork?

Beginner dancers usually shy away from learning Salsa shines (footwork) because they do not understand their practicality or value, yet.

The benefits of Salsa Shines are several. They can:

A) Improve your timing – If you get lost in the middle of a turn pattern, you will be able to get back into the beat more easily.

B) Improve your body movement – If you want to dance salsa, like a fish swims in water, shines are a perfect way to loosen your body and look more “Latin”.

C) Expand your spinning abilities. – It is more difficult to spin by yourself that to have a partner spin you. If you can spin in shines, then you can spin twice as much in partner work!
