For size 14, you're going to have a hard time getting good shoes that fit. I wear a size 13. Go ahead and mark off KO's, Ariakes, Five/Tens, and Feiuyes. Too small.

You're going to have to look for some basic running shoes that will help out. I love the Nike Dart series (I just bought a pair of Dart 9's) but I don't know if they go past 13. If you can find some basic running shoes that have a (mostly) one-piece sole, then you should be in good shape.
