Fully automated vehicles may still be a ways off, but testers said that the full auto-pilot ski boot is here and it's called the Fischer RC4 105 LV VAC GW! Perfect scores for both edge power and quickness supported testers' comments that this boot skied well no matter what the ski, snow surface or terrain. Testers said that while the 105 performed more strongly than the flex index would suggest its greatest strength was its seemingly automated turn entry and strangely intuitive forgiveness of mistakes--like it knew what was being asked of it, they said. Easy to ski, fun to ski was the mantra.

This is a consistently snug, low-volume fit, testers agreed, which is nothing to sneeze about any more. So those skiers who have struggled to find narrows that actually fit as such can add this one to their short list for early season try-on. The stance angles were right where testers wanted them to be and the flex feel against the leg was ideal, they said. For a 105-flex narrow class fixed-cuff boot, testers said it went on and off more easily than expected.

There wasn't a BOA option on this model and testers were just fine with that, happy to slide in and buckle up using four normal buckles and a 45mm Velcro power strap. Nor was there a fancy ZipFit liner option for this boot and testers were okay with that too. In fact, they were provided a ZipFit prototype to test with this shell and they actually preferred the stock liner--so the takeaway is that this one's a beaut right out of the box! Speaking of out of the box fit, this is a Vacuum model that can be extensively modified with a variety of proprietary Fischer Vacuum tools--and we've had great success over the years testing this feature--but testers said this one's damn good just the way it is.
