Yes. The ISP proxies are locked on the USA Footsites (Foot Locker, Champs Sports, Footaction, and Eastbay) and Yeezy Supply during non release times. This is to prevent the ips from being banned or flagged on these sites.
We unlock and lock them shortly before and shortly after major releases and drop times so that you can run them on coveted drops. Our Discord has a channel that will notify you once they have been unlocked or locked.
If you want to know if the ISPs will be unlocked for a particular release, feel free to reach out to us on support chat and we can assist.
