i know there are ways to exploit this method. people will always find a way to exploit.
but each site should have an option where you log into your account for each respected site. enter your size/ sneaker request. and then they generate a code (raffle number). if youre selected, they send out payment links the entire WEEK leading up to the actual release. and let people buy in groups, instead of all at once.
also have this option open a MONTH prior to release, to cut down traffic.
i also think they should just plain stop selling these releases in stores, and have all pairs allocated online. with my method or something like it, more pairs will be available, with a larger window, depleting web traffic. and ensure the safety of people by avoiding these lines/commotion.
