OUCH! Yeah, Sketchers are definitely not for running. They are more lifting/casual type shoes.

I highly suggest New Balance . . . These are the shoes that I have and they are super comfy:

My Running Shoes

But like Sara said, just go to a sporting goods store, go to the running shoes and start trying some on. Someone will help you. But I would definitely say it's your shoes, especially after hearing that you try to run/walk in Sketchers. I should also add that if you get a good pair of running shoes, only run in your running shoes. Don't lift in your running shoes (especially if you pay big bucks for them) because lifting will wear them quicker and different. You'll wear them out quick enough on the treadmill!
