Tips for a better lower leg when jumping?

[Flying_Form]

My actual jumping position is quite good and fairly textbook but recently in videos/photos I’ve noticed that for bigger fences my heels don’t stay down in the position that they do on the flat - they go level with where my toe is (they don’t go up YET ?). My actual leg position is still and secure but my heels go up and it’s annoying me so much ?? I don’t know if because the fences are bigger I have to fold more and I’m putting my weight in my toes rather than my heels? But are there any tips on making those heels stay down without making a conscious effort every time!

I was always told show the jump the soles of your boots on the way in and this means that you will show the soles of your boots the whole way over.

I treated myself to a pair of flex-on stirrups with the angled tread and they've been a game-changer over larger fences.
