I just looked these shoes up on Amazon. They cost $250-$350. Based on that I expect these are worn more by fashionistas than athletes.
Then you're clearly speaking out of ignorance -- that's exactly what a high quality pair of squat shoes cost. You know what those are used for? Squats, and about nothing else. Good specialist products are often expensive. Just because you don't like expensive things doesn't mean they don't have value.
Side note, anytime I see anyone snidely use the word "fashionistas" I know they're creating a false narrative about whatever it is they don't like, and it's almost never grounded in reality, only ignorance and resentment.
Although I'm all for "specialists" (sic) shoes, I used to do half squat jumps (yeah, jumps with huge loads) when I was on the Canadian high jump track team in the 1980s and my shoes were plain $80 pairs (in today's money). Pretty sure my use was near the most extreme you could do for any shoes (the jumping with a load and the need to not be destroyed in the process) (don't try it at home folks ;-) and so I find the claims about those shoes very very dubious (not just nike ones).
The only expensive shoes I had were my jumping spikes and those were second hand and probably $100 at most new ($200 dollars now).
All those shoe's prices are mostly for the fashion angle, not the so called "technical" angle"; that angle is in most case, a marketing spin. I do buy those kind of shoes at liquidation outlets (Nike, Rebeok, New Balance, whatever) for 1/5 the price they're sold new, so I don't have to worry about spending loads of money on shoes.
I'll have to disagree with you, as do the professional strength trainers I follow -- Mark Rippetoe, Alan Thrall, olympic weight lifting teams, etc... Stationary squats are an entirely different movement and use case than box jumps. The point of squat shoes is to enable obtain proper depth while keeping the shins more upright which means less movement arm at the ankles. It's just physics. But the quality build is what helps support your arch while also keeping a flat surface area and not compressing under load (some squat shoes even use wood for this). A good pair will last your lifetime of squatting.
Runners can go on in a similar fashion about the virtues of expensive running shoes. As can climbers, hikers, etc etc..
99.999% of people who buy these things, even people that do squats in gyms don't need this and you know it. They're weekend warriors and seriously they'd be OK with 3 times cheaper shoes. It's mostly marketing that made them think they're worth paying all that money for a specialist shoes. Most of those people shouldn't do full squats (and for most people its pretty dubious exercise considering how weak the muscles / ligaments around their knees are). There is a reason tendonitis bellow the knees is so prevalent.
Also, I don't think you realize hw much weight high jumpers are jumping with, no normal squatter does that because well, they're not trained to and likely would destroy their knees 20 times coming and going if they tried. It requires a huge amount of power at all angles. Someone who jumps several feet of the ground with big loads on their shoulders and lands them softly... High jumpers are deceptively powerful because most are very tall, which hides the muscle mass.
