So true, a foothook is by far the very worst mechanical "connection" possible
Almost a perfect crowbar to rip the insert or deck apart
So anything that can distribute, and flex, is way better on a foot hook in order to avoid damage.
A normal footstrap has very little mechanical stress, compared, as it has the force pulling almost in the deck direction, instead of up like a crowbar, thus much stronger in this respect.
So a foothook is much harder on the board/inserts, no doubt at all, no matter what.
On the other hand, you could also say: If it has ripped your deck, isnt that better than your foot getting stuck and ripped ?
Dont know, but the crowbar effect is one reason why I havent used foothooks - the other is, when you have learned foiling, strapless is often chosen, and for jumping foothooks are not worth much, compared to straps
