Are the Keen sandal clipless version sandals stiffer-soled than regular Keen sandals? Because I have 2 pairs of normal Keen sandals and the soles are not what I'd describe as stiff at all, they are soft and bend-y...nice for walking and hiking, for sure.

I just ride with my usual comfy shoes (insulated hiking boots in the winter, walking/jogging shoes in the summer) and PowerGrip diagonal straps, on platform (touring) pedals that have some nice teeth. I like the Merrell Ventilators in warm weather- they have some mesh openings that let your feet breathe and they feel nice and cool yet supportive. I enjoy the feel of a decent arch.
