On a crouded dance floor I have used the technique of 'planting' my feet; one foot infront of the other in a relaxed stance, bent at the knees. From here I can move my weight forward or back, twist and bring the lady to one side or another, and move the lady in the (little) space available. Feet don't move. Unfortunatly this sometimes leaves the back foot open to being kicked or trod on on the odd occasion; no plan is perfect.

Another other I have been known to do is not take any steps bigger than a shuffling step and use lots of baskets, combs, and close moves.

One technique that was mentioned elsewhere was moving your partner into the space you vacate and you moving into the space that they were in. (ie "slot" or "cross" dancing) there is very little in backward movement using this technique: you can always see where your partner is going and where you are going.

Personally I like the option of sliding the foot instead of stepping... less dynamic, but smoother.
