Thanks for all the good ideas guys. I think I'm naturally prone to 'ankling', but now I'm a bit leery of it. I had a nasty case of what felt like tendonitus in my ankle this spring, and advice here on the forum suggested using real bike shoes instead of sneaks. I bought some mtn bike Shimanos and haven't had the ankle complaint since. I'm still hoping that thru continued usage my 'upstroke' on the clipless pedals will gain a little more power.
