I am looking to get new MTB shoes. I plan on doing epic rides (5+ hours) and lots of normal trail riding and maybe a couple races here and there. I do tend to be hard on my stuff on the trail (rocks etc.). My current Diadora Gekos only lasted about 1 year before they needed to be replaced. Money isn't really an issue iin determinining which ones I will get. I have tried on Pearl Izumi Vortex II and they fit well. I also tried on the Sidi Dominator 5s but the store I went to didn't carry half sizes so its hard to judge.
