A sneaker proxy is usually a hidden server or a P2P private peer. It has to be reliable, preferably on a broadband connection and you should get more than 100k IPs in order to rotate between them (also known as IP rotation). All other proxy providers use proxies called “Residental Proxies”. The best performing proxies would be data-center proxies because the connections are rapid enough to get to sneaker stock first. Supreme, Shoes, Sneaker-n-Stuff, Nike, EastBay and FootAction require fast datacenter proxies on the most difficult releases. Using free or slow residential proxies will leave you with a disadvantage over datacenter proxies.
