The 2017 Elan Insomnia Power Shift is re-introduced for 2017 with a few key updates to the construction. The Insomnia has always been built for high speed performance and still is. The waist width of the ski was trimmed down just a hair to 73mm, making carving that much more precise. The bindings also received an overhaul, hence the new name of Power Shift, while the old version was called fusion. The Elan Insomnia allows advanced to expert level skiers to engage in short to medium radius turns at higher speeds on the front side of the mountain.
