The solid lifters are not Techica ones but from boot fitting suppliers like SVST. Personally I am willing to give up the N-N-Nth degre of a solid sole for something easier and safer to walk in. But I will admit I am not always on a race ski. I would be interested in you put a set of these soles on one boot and the solid smooth lifters on the other if you would notice the difference in a race course.
Yes, would actually be possible as I have a second identical pair with the solid lifter set up that has hardly been worn. The other thing I would be interested in is whether anyone has actually done any back to back objective/ measured testing on the comparative release values with the different lifters
