Simply stated this liner provided the best fitting boot I have ever had. The fill material is so sensitive, that one twist of a buckle can make the difference between too tight and just right. Because the material conforms so completely around the control zones of the arch and ankle, there is literally no need to buckle down the shell tight in order to control the foot/boot/ski interface.

The boot can be almost loose, yet the overall fit remains tight. Previous liner/shell combos were always a compromise between snug fit and cut off blood flow.

The Problem: Low volume foot, narrow ankle, high arch and instep; and wide across the ball. Add a good size bunion. Closing down on the shell to secure the ankle shaft resulted in too much pressure on the high instep, which cut off blood flow to toes.

I bought the Plug Neoplush (neoprene vs. leather interior) from Superior Ski. (Steve Bagley 801 209 6681) .

They were installed in a pair of Lange Comp120 LF (low fit). The install was easy. I heated shell and liner with a heat gun to approx 200 degrees. Then insert foot into the liner; close the liner with the Velcro strap and pull up the laces; insert the liner (with foot inside) into the boot. That was enough to ski the next day.

One item of interest is that I must first insert the foot into the liner; then insert both into the shell. The Zipfit conforms so completely to my thin ankles that it leaves a relatively small opening which is impossible to insert my foot into while the liner is still in the shell. I use a pair of needle nose vice grips to pry open the lower part of the shell to facilitate this process. It is actually easier than forcing my foot into boots as I used to do. I can put away that WD40 which help squeeze my foot through that narrow gap!

The Zipfits have a cork silicon filled bladder on either side of the ankle shaft running down and around the instep. The tongue the same material. This material molds so well that, for example, the long narrow achilles tendon is perfectly molded down the back of the liner into a trench about an inch deep. It blends into and wraps around the ankle forming a very tight heel pocket.

Concerns about the pliable or dynamic characteristics of the silicon cork material were never a problem. When putting the boot on, or taking it off; I could feel the liner material reforming a bit. However, once the boot is on, and buckled down; there was never any sensation of the foot moving around within the liner. In fact, after a couple of hours skiing, I could undo all my buckles and still ski with a significant margin of control.

I have spent 10 years; bought 7 or 8 boots; visited dozens of boot fitters; spent a couple of hundred hour sitting in shops; and spent thousands of dollars trying to get a good fit. Zipfit is by far and way the best remedy I have found so far. I have had two sets of Conformable foam liners blown into both a Lange and Rossi shell.

I have cut up liners, sewn together liners; changed tongues, and added pads. I have blown out bunion bumps and melted shells with my feet inside to get them to mold to my shape. I even thought about surgery on my feet to make them fit the boots! You name it; I have tried it. Zipfit worked for me.

These are not cheap. They run about $350 shipped. However, they are worth every penny when I can ski all day, with warm toes, all the while enjoying great side-to-side boot control.

Thanks to all the Bears for their help. Gordo
