So there's been a ton of threads about boots that don't cause shinbang and from what I've seen, "buy Full Tilts" has been the common answer but in fact, isn't the only answer.
I figured I should chime in on this since I do have a little experiance in fixing this problem over the past 6 years.
Boot Fit: it goes without saying, if your boots don't fit you're in for some trouble beyond shinbang
Booster Straps: they help a little bit but not really. If anything they will give you better rebound out of your boots and perhaps a little more shock absorbtion
A lot of people have said "shinbang is caused by skiing backseat" this is spot on! Now a lot of people think they don't ski backseat but because of bad habits developed over years of skiing, their natural stance is backseat and they can't feel it.
The real problem is the forward lean on your boots. The answer? More UPRIGHT BOOTS!
This is why you all scream "FULL TILT" without even knowing why. A more upright boot will the most with shinbang issues because you are not being forced as far forward by the boot and therefore the strain on the shins in reduced.
Boot Recomendations: There are a ton of boot companies out there that offer a boot with a more upright stance. Here are a couple of examples FULL TILT, DALBELLO, SALOMON, ROSSIGNOL, etc...
Now if you have a good and I do mean GOOD bootfitter, they can take the boots you currently have and make them more upright by grinding away plastic at the bottom of the back of the cuff. BEWARE: IF THEY MESS UP YOUR BOOTS WILL BE RUINED!
Hopefully this helps with the shinbang discussion
