The number of Adidas proxies you need depends on a few factors including the level of demand for the release, the limitations set by Adidas on purchases, and your budget. For highly anticipated releases, it's common for sneakerheads to use hundreds or even thousands of proxies to maximize their chances. However, for less hyped releases, a few dozen may suffice. Always balance between the cost of proxies and the potential value of the sneakers you're trying to cop.
