i wore these for a 2-day through hike of the narrows in combination with neoprene socks and was very happy with their performance. most people rent the 5.10 canyoneering shoe, which may be even better b/c it offers more protection for your feet (the mesh panels on the salomon won't help you if you get a foot wedged between rocks). i would definitely recommend neoprene socks b/c they keep debris out and keep their shape, which will help prevent blisters. if you're just looking for a one time use, it's easy (and not too expensive) to rent the 5.10 canyoneering shoe. but if you already have the salomons, or want to purchase a shoe that you can keep using for anything & everything, then i highly recommend the salomons. one note - i have the older model and they have held up great except for some tearing of the mesh, i can't speak for the quality of the current model
