I gotta say, I feel your pain. I wear a size 16 US and gave up on clipless shoes. The ones that are available (very few) unfortunately break my budget.
I use MKS Touring road pedals with clips/straps on my road bikes, paired with New Balance cross-trainers. Usually do three centuries and many miles a year, and have gotten by very nicely. No one gives me any guff about not being "clipless" (maybe being 6-9 and seated on a monster bike has something to do with it). Good luck, though, because I understand the strap thing isn't for everyone.
