The Vapor L has the same basics than its brother the Vapor V with a few changes.
First of all, it is a lace shoe, giving it a bit more versatility and adaptability to the climbers foot. Furthermore, the sole is one continuous piece from toe to heel giving your foot a bit more support and stability. Finally the shoe is vegan, hence no leather has been used and therefor the shoes shape won't change too much even after countless climbing sessions.
