I think Trail Running shoes make good cycling shoes. They are comfortable enough to run in, but are stiff enough to be efficient when cycling. The ones with Gore-Tex or other waterproof linings will be a little warmer. But, as stated, will not provide as much ventilation in warmer weather. If you don't like clip-less pedals, might I suggest Power Grips. It's a simple strap that crosses the pedal and provides shoe support, but are easy to get in and out of.
