I have ridden SIDI shoes over the last 15 years. I decided long ago to not use any thing else. Wires top anything SIDI has put out making them the best shoe period in my opinion. They have great arch support, extremely comfortable on 3hour plus rides and the venting is makes a huge difference in keeping my socks drier and feet cooler. Maybe this is not as big a deal on shorter rides but on long ones, it really matters.
