Pfft. I just replaced my 14-year-old Dominators -- after MTB racing on them for many of those years. The shoes are still totally ridable, but the soles are finally starting to delaminate from the uppers.

I have 10-year-old Genius 2s that are just dandy. I don't ride them because I got a free pair of carbon Nike 10//2s last fall, but they aren't looking like they'll last more than a couple of years -- so I'll have to pony up for some carbon Sidis
