I'd rather not wear heels as I drive in. I also don't really like ballet shoes, but have been told my Dr Martens aren't smart enough.
I like slightly odd choices, like T.U.K. and Irregular choice, but obviously they need to fit with work stuff.
ETA: Also my back is KILLING me from being squished in a bad chair all day. A new chair is not an option. What exercises/stretches can I do for it?
