There are reputable websites doing exactly what you are looking. There are some that also open the box for you to check if everything is fine before sending it to you, so you don't waste your time and save money if there is something to be returned
they don't take reshipping address anymore.
I've obviously considered it.
in past I have used shipito.com (I'm in EU). And worked fine. Can recommend them
EDIT: Just noticed they have affiliate program. So if you are willing to? PM me for aff link.
How it works?
They give you your own US address (there is option from multiple places on both west/east cost)
After they receive the package, unbox it, provide you with pictures. You check them, say everything is as should be, then pack it again and resend to your address.
I'm aware of how reshippers work. The problem right now is that reshippers uses an address which can easily be detected by Nike. As a result, its pretty much impossible to get it shipped to a reshipping address, ie. warehouses.
