My (original version) RS's have over 100 days, mostly touring. Walk mode has a little bit of play, but I've only had an issue changing modes (from walk to ski) a few times. Kicked my boots together...

Alien RS is smaller all around. F1 is somewhere in the middle

Scarpa says they fit the same, but I recall older Scarpa boots with the same last but different buckle configurations fitting quite differently than each other.

Same here. I've got about 30 resort days and 50 touring/ ski mountaineering days on mine. Several 15 mile+ days with heavy pack and no blisters. Even some ice climbing. Grivel G12's fit better than...

That was my first thought. I have a very snug fit all around except in front of my (rather short) toes. I don't need the two lower buckles to be tight at all. Perhaps the pebax version folds under...

Weird. I've skied many days or both (27) and found them to fit the same. Had the same punches on both.

I believe at least some Dynafit race boots break on the half size as well. No idea why. It's dumb.

Anyone has issues getting their RS's punched out? Should I go to a bootfitter with experience working on nylon boots? Or will the guy who mostly works on race boots be ok?
