Maybe you're using the wrong shoes.
I've found the old Shimano MT31s to be walkable for miles. Medium stiff sole. I now have PI X-alps that seem to be designed to be stiffer from the cleat back, but more walkable due to the shape and flexibility of the sole in the toe area. Since you're considering clips or platforms, you're obviously not concerned with having a stiff sole anyway.
FWIW, I use the above mentioned shoes with Speedplay Frogs.
