Ooh, ouch! Any point in writing to the shoe manufacturers? I have some super-duper Merrils and they're the best thing for my feet when it's dry, but on a wet surface they're treacherous - especially on a wet tiled floor for example. Going to the loo has become a dangerous sport - especially when floors are newly mopped.

I hope your elbow feels better soon - and do make good use of that experience in your writing.
