I've got the same exact pair - they are awesome, super comfortable and flexible.
It's important to note that as for any thin-sole shoe, it takes time to get used to what is much more like walking barefoot - your foot placement and posture changes, as you use the ball of your foot and your calf more. Think of it as the difference between running with a heel/neutral strike with padded running shoes and a toe-strike when running barefoot.
Re. longer hikes and rocks, the sole is well protected and quite tough - they are indeed built for hiking; consider walking briefer hikes in them for a while so that your foot / calf muscles to get used to the difference before taking on long and more exhausting hikes that increase the chances of a twisted ankle.
