sorry for taking so long to thank you guys for the suggestions. the boots work a bit better with the inserts but there's this retarded counterproductivity. My heels don't come out but the boots around the mouth area gets bigger because there's added resistance by the heel shims. Ha. Duct tape it is....Fixes everything from snowboard boots to bombs.
And just a helpful suggestion for yall. Never buy from a high school snowboarder who says "stoked" and "awesome" to describe everything from snowboard products to existentialist philosophy. Stupid guy was like "yea, i like my boots a little loose." dumb little turd.
I'll try the foam thing but i just need to make the top part of the boot tighter. Maybe i can't tie my laces right? Ha.
