Fastest Residentials

Im Looking for the fastest residentials possible for sneaker sites every time i buy some they are really really slow. Can anyone point me in the right direction?

You're going to need to reach out to each potential provider and ask them for their proxy speeds and ask if there is a guarantee. Remember "back connect" or "rotating proxies" are botnets and thus depend on the speed of the infected computer so speeds will greatly differ.

Most providers of residential proxies have a money-back guarantee, so (as mentioned above), you can contact them and ask them to test their proxy pool on sneaker websites.

Bear in mind that by default residential proxies are slower than datacenter proxies because the routing is usually longer.
