I've only had 4 pairs of cycling shoes in 10 years. I started with Specialized shoes about 10 years ago, moved to Shimano, and then bought a pair of Sidi Genius 7s. I liked the Sidi's on the bike, but kept getting sore feet, especially when I stopped for a break. I decided to persevere with Sidi and bought a pair of Ergo mega's (wide fit) I'm very impressed with them, and have reached the conclusion my previous Sidis were just too narrow. I have enough room for winter socks, they don't have vents underneath, which aren't needed for about 95% of the time in our climate, and the dials are much better than the ratchets I have had previously. A fairly expensive option, but I'm really glad I bought them.
