1. The most important thing for the reduction/elimination of shin bang is good fitting boots. Go to a good boot fitter and let them analyze your foot. Do not go to a boot fitter wanting a specific boot, go to the boot fitter and tell them what type of skiing you are doing, your ability level and explain to them if you have any foot/leg related issues. Try on every single boot they give to you do not not try on a boot because it isn't a park boot or it isn't the brand you want. A good fitting all mountain boot (even a race boot) will be a million times more comfortable and perform better than a poorly fitting park boot.
Get a custom made footbed not a trim to fit footbed a proper custom made footbed molded by a good boot fitter specifically for your feet. I use Sidas custom footbeds they're great and have made my boots way more comfortable and significantly reduced shin bang. Custom footbeds are quite expensive but worth every cent and they usually last for two - three pairs of boots. The most important thing for buying boots is never buy boots that are to big. I made this mistake when I first started skiing, I went and bought the cheapest boots I could two sizes to big, my shins and feet got raped so hard. Never buy boots that are to big they suck in every way possible and I can guarantee you, you will get shin bang.
When you buckle your boots make sure you buckle them firmly, it may seem that riding around with your boots done loosely will be easier on your shins but it's not. When your boots are done up loosely your feet are more likely to slide around and cause issues also you lose a lot of control with loose buckles.
2. The second most important thing to reduce shin bang is proper skiing technique. You could say this is the most important thing but not everyone is Tom Wallisch so unfortunately us lesser people do land backseat and having good fitting boots will reduce the impact of backseat landings on your shins so I think good fittings boots is the most important thing.
Learn to ski with your pressure forward on your shins, make it a habit to always try to have pressure forward and not to lean back on landings. Learn to ski outside of the park and be able to carve and ski groomers really well.
3. Exercise and build leg and core muscles. Having strong muscles is very important for being able to have the proper technique and keep your weight forward.
I bought a exercise foam roller it cost me $30 (NZ) and it's really good. The foam is pretty solid and not soft which is a good thing.
It's like this one just the little bumps on it are smaller:
I just put both my shins on it and roll backwards and forwards on my shins for a couple minutes, when I first got it, this was extremely painful and I could barely roll on my shins for 15 seconds but now it's a lot less sore and actually feels quite good. I roll on my shins everyday and before I go skiing I think it has really made a difference and my shins are way less sensitive. It's also great if you roll your back over it because it cracks your back really nicely.
4. Finally the last thing and probably the least necessary is buying some form of shin protection to actually use during skiing. I bought a pair of shin shields out of desperation while I was at Cardrona last year because I was so sore due to my oversized boots. They actually seemed to really make a difference and reduce impact on my shins while not impacting the performance of the boots. Now I always ski with them honestly I think it's more of a physiological thing, just the thought of having some form of protection may reduce the amount if pain felt but anyway I think they're awesome and worth a shot.
