First day w/new Zipfits (Gara LV) -- Starting from the start, I have to admit I was nervous about being able to manipulate the entry into my shells (Lange Shadow LV). I practiced a couple of times at home and had such a terrible, and unsuccessful time that I thought I'd have to resort to putting the liners into the shells and then putting them on (not the recommended practice b/c, according to Zipfit, it can alter the formation of the cork in the heel).
Enter the Kulkea heated boot bag - an early Xmas gift. I put my shells in the bag overnight on low and about an hour before leaving the house I switched it to high. Still trepidatious, I put one boot on in the house and decided to put the other on in the parking lot (I have only a 4-minute drive). I was shocked at how easy it was to "world cup" into the shell. Sticking to my plan, though, I kept the first boot on and plugged the bag w/the second shell into the car outlet and set it on my heated passenger seat. In the parking lot, the second boot was even easier. The Zipfit slid right into place w/o having to use silicone spray or my boot horn (I was prepared for battle). I think I have my answer.
Skiing -- Pretty effing amazing. I've never been so locked into my boots. No heel lift or slip, no flop. The Zipfits gave me a level of confidence on a first day that I've never experienced before - this is saying something, b/c I was on a new, narrower, stiffer ski as well (Stockli Montero AS). Total control. Total, instantaneous engagement. I am beyond pleased.
