What appears to be an updated boot from Scarpa with some features Alien RS. Lower shell appears to be like the current Alien 1.0, but with covered Boa system borrowed from the Alien RS. Does the lower shell maintain the existing internal laid-up carbon fiber internal skeleton or does it utilize the carbon reinforced injection mold plastic of Scarpa's RS boots? The CF reinforced injection mold material is reportedly stiff, but difficult to punch! A Scarpa Alien RS 1.0?
