CopBot for Chrome
More About CopBot
CopBot will constantly refresh Nike's twitter feed and as soon as the shoe that you want is released and Nike tweets about it, CopBot will click the link for you and then automatically add the shoe in your size.
CopBot also works with early link. It will constantly refresh the early link page until the shoe is released, and then add the shoe to your cart in your size!
This sneakerbot works for Nike.com and all updates are free for you!
