Smitty, are you sure your shoes aren't too small/narrow? I had to sell my Doms...I kept getting numb, pinched toes. Eventually I started having nerve damage on my larger/wider right foot (in the form of a deep itching sensation that only went away once I switched to a significantly wider men's LG shoe). If your numb issues are from a shoe that is too narrow, then I would HIGHLY recommend against any Sidi women's shoe. And unless you have a really wide heel I don't imagine that the men's version would work, either. I had issues with heel slip on my Sidis. I have duck feet, though.
