stiffer may work they are lake mb shoes.
I tried more tension and it does not fix it. I jsut don't want to buy new spds and find they still do that. tried eggbeaters and they were ok though you don't feel like your locked in and they make my right foot hurt (one size difference compared to the left) though going to their wider platform may fix it.
tried frogs again and they are fine but you walk on the cleats and I forgot what a pain that is. plus they don't let my heel turn in enough or if I let them then I come out too easily. but if it was not for the cleats and walking I would go back to them. I hear the times are far harder to get out of. thats a problem since I am not used to that.
