Replying to Shin bang can sugma shmeat

Got shin bang real bad one day this year from not doing up my boots right enough and it comes back really easy every since. Trying to not land backseat as much but sometimes it’s hard as I taught myself how to ski and never learned right from the start. Does anyone know if it’s a good idea to put the strap under the tongue of the boot?(ft b&e) or if over is better. Should I invest in stiffer tongues?(6 flex rn) or am I just that shit at skiing
