EC2 is C2 Technology enhanced, EC2 is Elliptical!
We added Elliptical Camber, slightly shortened contact lengths and a smoother, more powder friendly tip and tail entry. The Elliptical camber moves the apex of the camber inward (closer underfoot), which helps distribute tip and tail pressure more evenly, provides a more focused pop, and creates better suspension to absorb big landings. The slightly shorter contact lengths make it more agile and user friendly on hardpack and pow. Win! Win!
