Contour 4 Technology is a revolutionary advance in performance ski boot fitting and engineering. The anatomical contours of the inside boot-shell and the innerboot lasts are perfectly mated to precisely map the shape of the typical high performance skier’s foot. A little extra “space” is molded into the inside of the boot shell at 4 critical fit points: ankle, heel, 5th met atarsal, & navicular. Out of the box, Contour 4 Fit Technology delivers all the comfort, precision, and control of a close fitting, low volume, high performance ski boot that has been “punched” and “stretched” by a custom bootfitter........with minimal need for “punching” or “stretching”. High performance has never felt so comfortable
