Replying to Shinbang ruins my progress and skiing

Its holiday season and I‘ve been trying to get some new tricks down. After about 1-2 days of intense skiing I get horrible shinbang. I‘m riding the ft drop kicks and got them custom fitted in a ski rental, I‘ve installed boosterstraps on them and I‘ve tried gel pads and different ski socks while skiing. The pain just won‘t go away and I feel like I‘ve tried almost every single thing possible. I might just try some other boots, but I‘m not really a fan of that Idea since the boots were super expensive. Any other advice?
