Replying to Shin Bangers

Recently I have been getting bad shin bangers more near the bottom of my shins on the front. I have tried a few things along with shin pads to fill extra space. I read a few different things on here such as shaving your legs can help because the hair can rub and fall off leaving bruises on the shins. I don't think it helped really that much, but it did change a bit. I tried tightening my boots down a bit more to again try and get my boots fit as well as possible, but I only felt more pain. I have already heat molded my liners as well. My thinking is that my boots are probably just a bit on the big side and I need a new pair :( but am not to sure. I own a pair of Dalbello Panterra 120 with a 3 buckle system if that helps out at all as well.
