Bangkok is a bit too filthy for sandals, but I wear shorts. The Thai fellas mostly don't, of course.
The basic rubber flip flops provide no support at all, but the ones I pictured appear to have some support and a bit of a heel. Anyway, a 10-minute walk to the beach doesn't make a walkabout, so support isn't all that necessary. When I'm at the pool or the beach I'm on the piss too, so I reckon I'm slouching - a heel won't help. And the sand is too hot for me feets.
