The Crispi Evo NTN Telemark Boot is a superbly versatile telemark boot. With a very slightly softer shell and bellows than it's big brother the EVO NTN WC (World Cup), this boot still packs plenty of power and is a good choice if you're looking for performance inbounds skiing or touring. The Crispi EVO NTN has dual density Pebax shell and cuff. The patented carbon fiber "Carbon Side Support" rigidifies the center of the shell and gives these boots great torsional rigidity and power transfer to the ski.
