Hi Calain, The C rating on crampons primarily refers to which type of boot they will fit on/work best with. C3 crampons will work with a fully ridgid boot for example, while C1 crampons have much more flex and will therefore work well with a softer boot. As the number gets higher, so too does the technicality of the routes that each crampons are suitable for. Hope that helps, Dave
