brushing boots

So I would like to buy some boots for my horse so I’m not paranoid when we jump. Once before he has knocked the jump hard with his front legs and tripped over so now I’m terrified he is going to hurt himself. I’m not sure if I should get brushing boots, open front tendon boots or closed front...

So my riding instructor has recommended I use schooling boots for my young horse on all 4 legs. Does anyone have any recommendations of schooling boots please? Thanks!
