On foam liners, yes the first ten days or so they are very tight and they need to pack out. Mine packed out pretty quickly and after the third day they weren't bad at all. By the 10th day they were perfect. Having said that, once they pack out and are comfortbale, I find it impossible to ski in any other liner. I spent two half days in Colorado skiing in stock liners. Every time I tipped hard with my little toe edge I was feeling pain up against the hard plastic. As well I was getting abrasion sores from rubbing against the liner. Most importantly, much of the one legged skiiing drills I do were much harder and in some cases I couldn't do them in stock liners, too much pain and uncertain balance. When you tip in a foam liner you are up against firm, but it's foam and it does not hurt the foot. I strongly believe that anyone that tries them and breaks them in will never go back.
Ron, I didn't say at the time, but my hunch was that the 174 was going to be too short. Glad you found something that works and that you love. I have never skied on the One so I will have to try them sometime.
