I need (eek) sensible, comfortable shoes
Well they certainly are sensible, and probably comfortable but even so, they are still horrid.
It all depends, you see. how old are you, and exactly how difficult are your feet? I am almost 46 and I have very difficult to please feet but even I would draw the line at those and I've worn some comfy but grim shoes in my time.
If you are under 60 and not in immediate need of bunion surgery then I'd think twice. I doesn't need to get that bad just yet.
Incidentally, I have some Gabor sandals which I LOVE. Very comfy and really quite pleasant to look at, providing you are not under 35.
