Not sure is all is resolved, but maybe. I tried my old Shimano clipless shoes (with cleats removed) with my old MTB flat pedals attached and it proved to be treacherously slippery. I didn't find any shoes in my LBS that fit and decided until I got around to shopping online for some, I would try the MTB pedals and some old Merrell hiking shoes I had. The combination works so well I decided to stay with it until I see a good sale online. The hiking shoes do not seem any heavier than my clipless shoes actually. I am pretty happy with the setup now, but I will probably upgrade at some point. Or maybe not.
