Boots can be controversial at times, and there are a lot of myths running around about them, so don't feel bad. :)
With the ones you posted, they are a little bit of a 'knock off' of the professional choice SMB boots. They have been said to give tendon support, but some people claim they give TOO much support and when they come off, the horses get hurt. I have SMBs myself, but I use them only on hard days for extra protection. Usually I go with nothing, splint boots, or polo wraps if I'm ambitious. :)
When it comes to shock absorption--and mainly with jumping--a lot of the shock is absorbed through the pastern. When someone tells me that a flimsy piece of fabric can absorb the shock of a VERY heavy animal, I am skeptical at best!! :) Many people think polo wraps provide shock absorption too--they don't. The best protection, when it comes to shock, is to have good footing for the horse to work in. There's no way around that one. ;)
Splint boots usually have a strip of something--plastic, gel, etc.--over the splint bone, on the inside of the horse's front leg. They provide little, if any, protection to the back tendons. So when jumping, that's why almost everyone will use open-front--to protect all those tendons, not just the splint bone!
With the bell boots idea, it can't hurt to try! you might find that it rubs your horse's pasterns though, so... might be a trial-and-error thing. I think I'm going to try to splurg on the Cavello boots--they look like sneakers, and I want something to cushion the hoof for pavement walking--where in the easy boots just look protective. (nothing wrong with that, though!)
