Have heard about problems associated with all the clipless systems so I don't think there is an easy one on the market. Certain manufacturers do have tension screws on the pedals that you can adjust to make them tighter or looser in operation and the only one I can talk about is the Shimano SPD system. They can be set up loosely but the first thing I do on these is to wind the screw in to give me near maximum tightness- just so I don't pull my feet out of the pedal on the upstroke.

And I had my first Club Tombay fall on the road bike today. That is after 5 years of safe road riding. Just forgot to unclip when coming to a standstill and over I went. Now MTB's are different- If you don't fall off with those things- You aren't trying hard enough.
