I got to see the demo for BootDoc Foam liners today for the Steamboat Ski Shop boot fitters this AM. It was very cool, Steamboat Ski will be offering these next season! The product has been around for a few years and even written up here before but it has had some significant improvements and I was really impressed so I thought I would write this up. It is a small world after all; I got to the downtown shop at about 10am and Brent Amsbury giving the demo! (he is a member here and owns Park City Ski Boot & Pethorthic)
The foam used in this liner is much different from the traditional high density, brick on a foot, material and is injected differently as well. The foam itself is a firm, but pliable foam, not hard or stiff. It provides a firm handshake firmness to the entire foot filling in all spaces. It will provide a more natural flex in the boot. It is not temperature affected so what you feel in the shop is what you get on the snow. I think the entire fitting process can be done is about a 1/2 hour. It cures in about 10 minutes. It also only takes about 2 hours of skiing to break it in. It should be good for 100-200 days depending on how much your foot sweats. There are 3 different liners, one is women specific. The MSRP is around $399.00 for the liner and fitting.
The foam is injected as a liquid which allows it to self-regulate and disperse more evenly and thoroughly. It is done through 2 tubes located on the back of the cuff. After the foot is evaluated and the correct liner is selected, the fitter can pad up any areas that need extra room including toe caps (see below). The insole is placed back into the boot, the tongue can be be moved to adjust for optimal fit. The liner has a lace up construction that is really only used for the fitting.; the laces are tied up as needed (again, you can leave space for big calves or tight for chicken legs like mine) The fitter mixes a couple magic ingredients into a bellows-like bottle and the mixture is shaken, The fitter attaches the liquid to the tubes affixed to the boots and forces the liquid into the liner until the right pressure is felt by the skier, the remainder of the liquid literally gets sucked back into the dispenser. In literally 7 minutes, the foam is set; the tubes are disconnected from the boot and you are ready to roll!
What I liked was the ability to have a liner that expands for harder to fit narrow/bony feet or those with bunions or other "deformities" You can place spacers on any areas that need extra room. For me, this could be ideal to create a pocket around my Poroneal area.
BootDoc also offers a foam injection tongue which is an excellent solution for those with hard to fit instep areas and bony thin tibs.
Although I didn't try one, I would have to believe this is a comfortable liner that still delivers high performance. The fitter who was our test subject is a long-time industry veteran who was blown away at the fit. He will be skiing it tomorrow.
Here are a few pics.

The liquid is injected into the liners. In this case, Brent is using a Fischer Vacuum shell previously fit. It can be done "hot" or "Cold"
