One question, how old are the skis that you ski on ?
If there are fairly new, those boots are not letting you get the best performance out of the skis.
Oh and your old custom foot beds are ready to be replaced, your feet change as you age.
We tell our ski house mate the same thing, he loves his rear entry boots, but his newest ski is may be 10 years old. He's over 70y/o, skis bumps all day without poles. Hey it works for him, but I would never ski like that.
As long as your having fun with the family, it more about getting out there. I guess you know you also provide some entertainment, for us gear geeks when we see you on the hill.
