The Ribelle family are a new generation of boots designed to allow people to move faster than conventional mountain boots. Core to this is the new ARG last shape, which has low volume technical precision, but with a noticeable toe spring, giving a much more natural and fluid gait. This is married to the new Pentax Precision Roll sole which has a technical Vibram outsole with bi-density PU cushioning, giving a much more natural feel and walking motion.
