I bought a pair of Keen Springwater shoes in early November. Thus far, I'm not really liking them. Maybe I'll like them more when (or if!) I break them in some more.
I have Speedplay Frog cleats mounted on the bottom of the shoes. The cleats fit fine and, when walking in the shoe, the cleat is sufficiently recessed so as not to make contact with the ground. Seated pedaling is okay with both the cleat and the shoe. The problem I have with this combo is that, when riding out of the saddle, there's significantly more pressure on my foot in the cleat area of the shoe than I'm accustomed to. Also, when riding out of the saddle, I feel additional pressure in the pinky toe area of the foot.
These shoes have a significant arch support, more support in fact than to which I'm accustomed. The bottom of my foot feels numb after a time, almost as if the blood flow is being cut off or restricted by the arch support. Moreover, after using these shoes for perhaps two weeks, I felt like I was developing a case of plantar fasciitis.
I've switched back to my old shoes, a beat up pair of Cannondale Roam shoes, to give my feet a break. Since reverting to using my old shoes, my feet feel better. I really ought to give the Keen Springwater's another chance, but, at the moment, I really don't like the way they feel.
