Scarpa Alien 4.0 Alpine Touring Boot Size:40 narrower than the F1 butBrand spanking new for 2022 is the Scarpa Alien 4. 0 Race Boot. Each race you're going to see at least one pair of these boots on the podium. Scarpa spent no expense designing these feather light (610g Euro size 42) uphill masters. Featuring a hand laid carbon cuff and chassis, they are both extremely lightweight and very stiff (110 Flex). Because of how sturdy they are, Scarpa added Pebax caps on the toes to protect your feet on demanding boot packs.
