Awesome, I can't say enough. I've been meaning to get a pair of 5.10's for a couple of years, but was always put off by the fairly wide fit throughout their product range. These were rumored to be narrower, and ended up fitting my narrowish feet very well. I haven't tried any other 5.10's, but these run a bit short as well. 11.5's are usually my size, but my toes bumped against the end of the shoe initially. Now that they are broken in , they seem to be just a bit roomier however, with toes no longer bumping.
These are easily as sticky as I need for lift-served and shuttle based gravity riding, and provide great protection and comfort. They pedal well, and are broken in after one day riding Downieville.
