Too fast, too furious. The Head Supershape i.Speed comes in narrower than all the other Supershapes, making it probably the quickest and snappiest ski in the collection. Its 69mm waist width profiles the i.Speed like a slalom ski, but with a slightly longer turn radius of 15m (at 177cm), Speed Rocker, and light-but-strong Graphene, it is way more fun for recreational skiers. If, that is, they want to go F.A.S.T.
