If they last at least as long as the original ones I will be maximally satisfied.

I like
the size fits me (I used it in my RIEKER insulated ankle boots instead of the original one, which wore out pretty quickly) I like the materials used (eva foam + wool lining) reasonable price (10€ to save 100€ of my shoes)

I don't like
Barefoot => I had to adjust the width in the little finger area according to the original insert. It was no problem, just something to take into account when buying !!!

I haven't tried them yet.
