Great Bootfitting Tool
I have really narrow calves and this was a huge help for getting a better fit on my lower leg and a more responsive boot. I combined this with the dualstraps 2.0 and it is a great combination. One thing I did was cut a little bit off the bottom of the pad to make sure it did not inhibit any ankle flex. It was really easy to do. Also, can't say enough about the amazing customer service from Craig.
Not that great the adhesive was not strong enough even after heating them up had to use another adhesive to have them stick
