If you have trim to fits, you may be elongating on top of the insole, causing toe issues because you don't have a custom. It may be simply that you have too much room in the instep of the boot and it isn't holding your foot back properly.
Take the liner out of your boots, take the superfeet out of the liner, and place the superfeet in the boot. Center your foot on the insole without the liner in the boot, and move your foot to about 1 cm from the boot and buckle the instep to where you would normally ski. Use your fingers to estimate the amount of room you have in the instep of the boot.
Next, move your foot to the front of the boot, to where your big toe is barely touching the front of the boot, put your weight forward and use your fingers to estimate the amount of room behind your heel.
