After using SPDs successfully for a couple years now, and liking them a lot, I recently decided to try some road shoes. It is a good thing to know more, isn't it? An offer too good to refuse on some Sidi Genius 6.6s popped up and I took it. Advice from Forum members influenced me to go with the Shimano SPD-SL pedals. Bought the same brand, same size of shoe, so I just swapped out my special insoles, installed the cleats and was good to go. Here's the result:
After a 35 miler in hot weather today, I can report that the changeover went well and was pretty seamless. It does feel as if the support platform is a little larger than with the SPD/A520 combination I have been using. Clip in and out went without incident although the feel is a little different... I'll have to be careful for awhile and not get overconfident. I did nudge my seatpost up a tad to compensate for pedal/clip stack height and I stopped after a mile and relocated the cleats a little.
The new shoes feel a little cooler and better ventilated than my others, but whether these will serve as a bulletproof cure for the hotspots I am prone to remains to be seen. (I fear that I will never be totally free of that curse.)
As to difficulty walking, it seems to me that all the "duck walk" talk I've heard is an exaggeration. I could walk around in these just fine and I don't see it as an issue at all. A hike up a mountain is not in order anyway.
Power transfer did seem a little better, but any shoe-induced performance increment did got encourage my secret fantasies about turning pro. More and more, I'm beginning to believe this rumor that it's the engine that matters!
Anyway... I like the road shoes quite a bit and will report back a time or two more... is a Tombay in my future? If all goes well perhaps I'll need to get some black ones for more formal occasions.
