I'd say the airbags are what you want if the pain only comes from landing jumps and the canting is what you want if the pain comes from riding in general. Plus I totally agree that you should get comfy boots with insoles if you don't have some already. They can make all the difference in the world.
Well, all the pain come from landings so it's a little confusing right now.
I'm between raiden phantoms and ride capos. Which would be better for a blacklist? And more important my knees?
