My running shoes aren't cutting it. When I DL/squat, my feet and knees pronate (is that the right term?) inward and it puts a lot of unnecessary strain on my knees. What are some good shoes I can get for wearing to the gym and possibly elsewhere? I'm looking for something like the Nike Shox (cross-trainers?)...no olympic/powerlifting shoes...just normal everyday shoes that will keep my feet/knees from pronating inward when I pull and squat.
