The HeatFit liner of the Edge+ Project boot conforms to your foot for a snug fit. The footbed of this boot is an HP anatomical footbed, which ensures a comfortable run. The adjustable wedge arch support and SoftWalk heel of these boots allow you to use these boots for walking instead of skiing without hurting your feet. This ski boot differs from the higher cost Raptor Project RS ski boot in that the Raptor Project RS is for more professional skiers, has a PU (PolyUrethane) shell instead of a SuperLight shell, has four micro-adjustable Racing Alloy buckles instead of three, and has the Racing Flex adjustment with rubber inserts. The Head Edge+ Project ski boot comes in a white/green color.
