Daven--that makes sense assuming some type of flex in the shoe. But I have seen some really stiff SPD shoes with very little compliance that offered less flex than the road shoe.
Mustang--that very well may be, if the other responses are, indeed, true.
Thanks for the responses. With what I'm hearing, my experience is beginning to make better sense now. After a century, I couldn't wait to rip my shoes off. I'm wondering if the 3-hole types would allow for more comfort. Interestingly, their are some road-focused egg-beaters out there, and those have very little platform to begin with.
