Foot discomfort with clipped in shoes can be the result of many different things. Cleat placement, the stiffness of the sole (some people find that too stiff is just as bad as too soft), the amount of float, how tightly one pulls the velcro straps, the shape of the footbed on the particular shoe you're wearing, etc. I too like to move my foot around a bit. So, I'm quite happy with my Speedplay pedals and Specialized Carbon shones. I've also learned that on long rides I'll reach down and loosen the shoes a bit so I can wiggle my feet around within the shoe itself. Personally, I'd never go back to non-clipped shoes for rides of 50+ miles. But, if your system works for you, more power to ya!
