My frogs felt funny at first, but once I got used to them I was very happy. The LBS put the cleats in the right place for me for now, and if I need them moved later I'll go in.
I'm sure if you have a particular problem after a couple weeks of riding the bike shop will be able to adjust it.
My left foot kept unclipping the first few times I rode, until my hip muscles got stronger. (I knew my left hip and knee are problems and could feel the weak muscles making my leg sloppy. So, I didn't run off to get that left cleat moved because I assumed I'd get stronger soon.)
Practice in your doorway, practice A LOT in the grass, practice in a parking lot, and so on and so on. Soon it will be so easy, you'll be amazed!
Love those Froggies, and congratulations!
