Women have to remove high heels. They can deflate the slides. Normal mens' shoes are fine. Actually, I've never understood why any woman would feel the need to wear high heels on an aircraft.

...it started from a comment I made quite a while ago to the effect that putting the issued pyjamas on, and removing ones' shoes, before take off wasn't the best idea. If you end up with something going wrong on take off, and need to use the slides (or get through debris/fire), the pjs don't offer much protection. The lack of shoes could be even more limiting.Going down an escape slide, with bare skin on the surface, will, at the very least, give you a friction burn....and they're long slides. Arriving at the bottom, into who knows what, in bare or stockinged feet, is equally unattractive. Whilst the pjs don't offer much protection, have a look around at what some passengers wear.
