I have really thick feet. Not wide, but thick. I guess it is from doing Taekwondo. Anyway, my problem is that I can find shoes that fit length and width-wise, but not enough height-wise if that makes any sense. So the top of my toes (especially my big toe) gets crushed whenever I walk and sometimes the whole top of my foot is just in pain whenever I wear shoes. Sizing up does not help, my feet just slide everywhere. Wider shoes are harder to find, but they still don't give me a good fit. What can I do to stretch shoes out (I do use shoe trees)? I'm tired of getting crazy ass blisters breaking in new shoes. I normally wear a 10D/E.
