Weird Pronation question?

When I walk, I over pronation. When I run I do not pronate, is this normal or weird? I use 680 new balance running shoes.

I am an "over-pronate FROR 'running and walking, and went to the physiotherapist to get braces. they are quite expensive, but definitley definitley definitley worth it!
