Better late than never.....
I was the first importer of BootDoc foam liners into the United States and since 2010 I have injected hundreds of
BootDoc foam liners with a very high success rate.
The original version of the BD foam liner did not allow foam under the foot area. It was finished like a stock liner with
a Strobl last. The feedback from the first few seasons was that the heel was not getting locked down sufficiently.
The liner was comfortable, but not 'grippy' enough in the heel pocket. BD turned to Strolz's liner concept where
foam is allowed to seep under the foot, if necessary, to improve heel grip. Strolz boots, because their heel area is
designed to tolerate a wide range of heel widths, must use a wider than normal internal heel width. Therefore the liner must take
up the slack to provide substantial heel hold down. Allowing foam to penetrate just slightly past the base of the heel
generates enough pressure to improve the fit.
Strolz, like any other good fitter, prides themselves in their footbed production, so they sell a full custom footbed with
every boot. During the fitting process the footbed is fitted into the liner precisely so that no extra foam will pass under
the arch area or directly under the heel.
This is also the case with BD liners. If the footbed is interfaced properly with the liner, and the customer is clearly seated into
the heel pocket prior to foaming, very little if any foam will seep under the foot. It is not always necessary to use
a harness or pull down handles to foam a BD liner. It is recommended to do so if the customer is lightweight, but most
people over 150lbs will not need to pull down during the process.
I spent nearly two weeks at BD's headquarters in Liezen Austria this summer, and one of the tests I experienced was the
difference between the two types of liners. The Strolz type lasting we clearly superior to the Strobl lasting that was produced
previously when came to providing improved heel grip.
But at the request of the North American market, BD will produce a new Comfort Fit liner with a Strobl lasting that does not
allow foam to seep under the foot. It willhave a little bit less heel grip, but the liner is oriented to the recreational skier looking for
a relaxed custom fit.
The strange underfoot feeling you are experiencing can be corrected with an acetone injection in the affected area.
BD foam is acetone sensitive and can be soften by injecting a small amount and then massaging with a ball peen hammer
to break down the foam.
If you have any other questions regarding the BD liners you purchased, please let me know and I can help you get them resolved.
