This is the exact method I plan to use with my next order.
I'm located in EU and I think it has a high chance to work in my case because in the past I've returned clothes and shoes in literally dogshit condition (stains, dirt etc) and I always got full refund on orders.
With Nike what you need to check/try to research is if the company Nike is outsourcing returns to (in your country) meticulously checks items that are being returned by customers.

Decided to drop an update on my suggested method.
It did work out on one item (the one that resembled ordered item the most), had to contact their CS to get refunded on rest of the items. Only had to send them proof of postage. If anyone might consider doing it in the future I recommend doing it partially (Order x quantity of items, place x-1 wrong items and 1 right item, get refunded for all items or only 1 ---> if only 1 contact CS and get a refund on everything else)
