So I've just started running and after about half a mile the soles of both my feet seem to swell in the area pictured below. It doesn't hurt, it almost feels like there's something stuck to my foot, like a thick bandage or as if my foot has a bump on it. I've looked at my soles and they don't seem any different. The feeling slowly fades back to normal during my cooldown walk after about 5 minutes. Just wondering if anyone else experiences this and if it's normal for a beginning runner.
