If you're experiencing numbness both before and after you got yourself "fixed" it could be a fit issue or an issue with your pedaling technique (that could be attributed to fit).
First, if you're feeling tight in your shoes, check out NorthWave. They come down to a 38 which might still be a bit big for you though. I've been told they're the widest Italian road shoe out there.
Second, I can't recommend Speedplay pedals enough. I LOVE mine and would never go back to anything else. The range of float is awesome and they allow for all sorts of shimming. Mine are currently blocked up with all sorts of neato shims for both length and leveling. The 1/4 shim for my "gimpy leg" has had an impact throughout my body. No more skootching in my saddle, no more ouchie lower back.
Speedplays also have a "cafe cap" you can get to cover the cleat. I carry them with me if I think I'm going to be stopping a lot or when commuting. I just walk sort of on my heels, don't try to roll over the balls of my foot. Never crashed on um.
I would really look at your fit though. As I mentioned I have a limb length discrepancy and the bulk of my hours long fit was spent tinkering with my cleats. If you're not in a position that allows you to pedal correctly then you're fighting a losing battle.
If your fit is fine, see if you can't get someone with expertise in the area, maybe a fitter, to watch you ride and see what your pedal stroke looks like. If I get tired I know mine gets sloppy and that's when I sometimes get that numb not fun feeling. A newbie friend of mine was having that, we worked on her spin and over time she was doing much better.
