I have some Power Grips on my commuter bike and double sided SPD clips on my road bike. The Power Grips are nice in that you can wear regular shoes but still secure your foot to the pedal. I find them more difficult to get into than the double sided SPD clipless pedals, but that's the price you pay. I've had them for 3 or 4 years and with moderate use they are still holding up. They're starting to fray a little but they mostly still have their form, making it possible to fit my foot in.

One thing to consider is your foot size. From your post I infer you're a woman, so this won't be an issue, but my size 12 foot is in the "in-between" region between their regular strap and the long one. The long one stuck out too much and seemed overkill and clunky. The regular one fits my normal shoes but I don't have room to add for winter boots.
