The only person who can stop re-selling is you. If people didn't buy from re-sellers, there would be no re-sellers - there would just be people with massive credit card bills and soon-to-be-repossessed cars filled with full size runs of sneakers. Yes, it's hard to resist buying a pair of sneakers you've spent months getting hyped for, no matter what the price. But pay it now and you'll keep paying it. End the cycle.
