Going on vacation in ~4 weeks to a place that's supposed to be MTB paradise. I've been a roadie-only up until now and am looking to get my feet dirty. I can rent a bike there but I'm going to need some shoes. Shimano SPD or Time ATAC compatible, size 45. Used is cool, cheaper the better but still good enough shape to use in case I get hooked. Let me know what you've got.
