Toe Problem

Writing this down makes it look very odd but here goes ..... after about twenty miles I'm finding my right big toe starts to go numb and remains this way for the rest of my ride! It doesn't hurt but is mildly irritating and I'd like it not to happen. I've adjusted the cleat on my shoe and tried various different setups. I've also tried to experiment with the way I am pedaling but all to no avail. Has anyone by some remote chance ever experienced something similar and by any even remoter chance found a way to stop it?
