I'm 330 lbs and 5'11 and I've a problem with my shoes, I wore them out to fast but from one side only, the outer side. So my ankle twist and that make my hip hurts, I change shoes frequently but the same thing happens all over again. Any specific specific features or characteristics I should look on a shoe?
You might want to read this page on how to select a running shoe. Sounds like you underpronate your walk. That is you walk slightly outward on your foot with each step. From the chart on the page you might want to try a neutral type of shoe.
