I'm solidly in the camp that thinks there is a place for a rear-entry boot. Like many, my Atomic Redster boot provides great fit and performance, but, they are an absolute PITA in entry and exit mode, especially when cold. My son and I have the same foot size, one time, and one time only, did he try to use my boots, any guesses as to the reason? I would not expect rear-entry boots to be embraced by the dedicatecd Pugski community, as it runs country to dogma to get the best fitting/perfoming boot available. For newer and lower skill people, they could just bring more people into the sport. It will be interesting to read the reviews.
A little antidotal story. When I returned to skiing, over 10 years ago, I used my Solly SX 92's, white with some nice pink highlights. Took a lesson at Alta, on the first ride up, my instructor assessed my boots as a performance hinderance. On the last ride up, she semi-apologized and said I was doing just fine in them. Two days later, I joined a husband/wife team at Snowbird who were instructors at Bellayre, pretty much the same scenario. Prior to the next season, bought a pair of 4 buckle Sollies, and, got welcomed to the PITA world of putting them on and off. Did my skiing improve greatly, it did, but, I also spent a lot of time working on better technique.
