Everyone wants to re-event the wheel...Gas peddle, tape on Zeppa, cut this cut that, insert after market this and after market that. Bottom line is the oldest technology of all is the human foot. Its real easy to get a great deal on all the wrong stuff and then chase the rainbow forever. Find a boot fitter that actually understands the normal and abnormal function of the human foot and start the process from there. Everything gets easy then. When a foot is in its most efficient position you will be surprised how much better it is able to flex the boot and then in turn load the ski. The Fischer vacuum system is awesome when utilized properly by someone that actually understands all of the nuiances of the process. Also not all human feet want or need to be in a abducted stance/position which in turn can make the bootgasm impossible for some no matter what you do.
Amen brother. The Force is with you and your ski equipment customers, no doubt.
