Pros: Fabulous fit, flexible when cold, slightly lighter in weight
Cons: Difficult to remove at end of day, no factory installed screw-on sole plates at heel and toe, inner shell plastic can exfoliate in hair-like threads
I have written about these boots in three other threads that deal with subjects related to either the 2012 or the 2013 models of Fischer Vacuum boots. Mine are the 2013 Vacuum RC4 Pro 130, so this is the proper place for my review.
After 18 days on the snow including 4 days of Masters racing, I am happy to report that these boots have exceeded my originally skeptical expectations.
Due to a combination of good luck by choosing a shell size that was not too tight and the advantages heat molding under air pressure, I have been very fortunate to get a comfortable fit that was only possible with my previous boots which required me to cut four 2" diameter holes in the shell in the ankle area.
With the Fischer Vacuum boot, no holes, no grinding, no punching.
The fit is so precise, that my feet will not slide out of the boot at the end of the ski day unless I pull out the liner at the same time. I wear Rohmer Silver Jet III wool and acrylic ski socks, not overly thick, but perhaps not the smoothest textile to permit foot extraction from a snug liner.
I have addressed the challenges related to foot extraction in the following thread:
After using Comform'able poly-urethane injected liners for 6 years in my old Rossi shells, it is nice to have a Fischer liner which uses open cell foam instead of the urethane closed cell foam. Open cell foam acts like a sponge and allows the humidity from my foot to condense within the foam and not in the sock. My feet stay warmer longer and feel dryer due to this.
My race times have marginally improved this year as well and some heads have begun to turn by people not used to seeing me nipping at their heels.
In spite of the price $1092 (includes 15% sales tax), this is the best purchase in ski equipment that I have ever made.
