It think many of the examples posted here are exactly what I was.posting about. They're almost all ugly and if they're not quite as ugly as the ones I've posted they're not quite comfortable either.
There is no middle ground. I think you need to own it and do it properly.
Gladiator sandals are surely not the thing? I have some reasonably comfortable gladiator sandals but I stopped wearing them a long time ago. To my eyes the chunky ones I posted are far more modern!
