hot spots...potential remedy
You can add or take away liner material. Adding involves adding bits of adhesive foam...and taking away involves shaving bits of the liner off. Put your foot in the liner, use a sharpie to draw or shade in exactly where the pressure points are. Then carefully remove a bit of the liner...I'd use a grinding wheel or a small grinding wheel on a drill or a wood rasp to just take-off maybe a 16th or 8th of an inche off that spot...A LITTLE GOES A LONG WAY...don't try to take too much off at one time. Then go ride and see if that does it, if not repeat. Once you get it tweaked then smear a bit of McNett freesole on top of the grind spot to keep the liner intact.
If you grind too much off, just build it back up with the adhesive foam.
