Hell's bell's [img]smile.gif[/img] I don't know about the color but the X-Wave boot is a nice boot. The higher the number the higher the level of boot. An X-Wave 6 is recreational, fine to upper intermediate/low advanced. 7,8,& 9's are progressively stiffer. We don't need a gawd-awfaul stiff boot with the shaped ski. But as I understand the X-Wave is still a rec. boot which is fine, still a dandy boot to own.
Someone here might know the flex index of the various X-Waves and their numbers. I can't remember right now. I think the X-wave 6 is around 60 or 70 flex, by Salomon's ratings. (flex index is not industry - wide standard. A 70 in a Salomon is not the same as a 70 in a Nordica, or Technica, sad to say, so it is difficult to compare the stiffness of a boot between vendors without actuallly trying them on.
Considering a Salomon flex number, 70 to 90 should do well for high intermediate to advanced. If the skier is advanced and doing some really aggresive turns or racing, and if the skier has enough length between the knee and the ankle to be able to flex a higher flex index then may be advantagous for that skier to go to a higher flex indexed boot.
Myself, being almost as tall as a grasshopper, I didn't have the leverage to flex my Salomon SuperForce boots at 115 flex index. I had them deflexed, which solved the problem. They now seem to be around 90.
Anyway, the X-Wave is a very nice boot. Have fun! Bob
