I've been seriously considering getting a pair of those. I have never ridden clipless before, but have decided to give it a try and already ordered a set of SPD pedals. I really like how those shoes look like regular running/street shoes. I was looking at them at Performance Bike yesterday and the one thing that struck me about them that I didn't like was the weight. I'm not a weight weenie type, but to me they felt significantly heavier than any other shoes in the store, including cheaper ones. But, i've read a lot of good reviews on those shoes, so maybe the weight really doesn't make much difference? I plan to use them for all types of riding if I get them, including everything from commuting, to mountainous 100+ mile rides on my road bike this summer. I'm not worried about them being heavy for commuting, but I don't know how much difference it will make by the end of a long day of climbing. Have you done any long distance riding with those shoes (In all the reviews I read about those shoes nobody mentioned that they've done any distance cycling with them)? Do you think they would be a good fit for my needs?
