My Experience with Injected foam linersI have a narrow, 94-97mm, forefoot width. Ended up getting Injected foam liners though was seriously considering Zipfit. I’ve now had two sets in two seasons. These were Tecnica’s house liner of a few years ago. and what I experienced hopefully would not be the same with Conformable brand liners. With the first set, the Right one seemed to degenerate its firm fit over not too many hours of skiing; looser and looser. The Left only a bit. So, the shop owner called and Tecnica sent another pair. I relined the following year. The Right liner leaked foam as the pressure of injecting intesified. Considerable padding was done to effect fit. The left liner required no padding. Fit being good after initial pack-out, the big problem I’ve faced is they are cold. Not a problem I’ve experienced with other boots unless I over-tightened them.
Cold when the ambient is below twenties, plenty cool in the twenties & cool in the thirties. Quite comfortable, when skiing in the 40 to 60 degree ranges
In trying to ensure that I wasn’t over tight with my boots, thus in some way restricting blood (heat) flow, I skied toO loose one day; which packed them out, at least one, if not two buckle notches. I’ve looked into heaters. Hotronic and Therm-ic both have very good reputation. I’m going that route. Having narrow feet can be rather expensive.
I’ve had considerable experience with ‘Fitters’; they are quite a variable, in knowledge and expertise. And it can be pot-luck as to who is working that particular moment.. I’ve tried to utilize those on the Americas Best Boot Fitters list, which besides being a marketing tool gives indication there has been some training done. It has been interesting. Study up so you know a bit.
Zipfit’s web site talks of warming the liner and boot before skiing, which may lend itself to condos, particularly slope-side, but not so well to the motel, breakfast on the way, 20-30 minute or more drive, put’um on in the parking lot set or similar. Which asks the question, what’s the toast factor of Zipfits?
Are these liners characteristically cold?, cool?, neutral?, or warm? in relation to Standard Stock Liners?- in relation to Foam? I’m throwing that out at the readership for possible answer, and for you to question. I’ve don’t recall hearing any bad reviews about Zipfits, or the burrito wrap type either.
