I'd stick to what I was accustomed to - I think you would lose anything you gained in the transition by having to adjust to something different, and you wouldn't be anything like as efficient. It doesn't take that long to change shoes, and it really shouldn't matter for a fun/social deal.
You would also be much more likely to FALL. Youre little tootsies are accustomed to doing a lovely routine at stops... now it's different.
