The toe clip I find centers my foot nicely. I toured on these in Tasmania recently wearing waterproof running shoes with their typical wider sole, you know the type where the sole becomes wider towards the actual tread surface, I think most are like that. Nevertheless, they aren't all that wide, perhaps without the clips it might be a problem. I took those because I got fed up with unsealed pedal bearings failing on me, so got a set of extra cartridges for them. Since I have the cleats on my cycling shoes a bit towards the back, I had to install a wooden block between the pedal and the clip to make sure the foot positioning is same as my cleated pedals.
*Now where did I put those spare bearings...?*
