Replying to Shin bang because I'm skinny

I've got roxa element 110's, and they are great. Super comfy and light. The only problem is I am really skinny and don't weigh much (130lbs). I have a booster strap and have tried buckling at as many different tightness-es as I could. I can't get new boots because I've only had these for one season so getting a lower flex isn't an option, unless they sell softer tongues for roxa's somewhere. I've tried cutting and wrapping a computer case around my legs to fill the boot, but it just cut off circulation and didn't stop the bang. When the pain was really bad I also tried gel shoe inserts with holes cut where my shin hits the boot. That helped the pain but didn't stop it from developing. Trying to get bigger legs by eating and biking, but so far it hasn't been working very well.

Anyone have any solutions? I think something to make my leg wider would be best.
