Late to the thread, but I wanted to get in another vote for BMX platform pedals. I'm recovering from arthroscopic knee surgery & am unable to clip into my speedplays for the time being (the torque and pressure of clipping in and out is too much for my menscotomized knee). The BMX platforms are huge and when used in combo with my running shoes are pretty grippy. One thing to keep in mind-- I raised my saddle about a centimeter since the combo of the BMX platforms and bulky running shoe sole has my feet a little higher than w/ my road shoes and speedplays.
