As long as the shoes are new and all of the laces and zip ties are included you're good. They have to check the shoes and pretty much take everything out and then put it all back together to make sure its good. And they re-lace all shoes to factory lacing themselves with every pair, even used.
Every pair of shoes you get from there is supposed to be like opening a new pair of shoes with wrapping and lacing
thanks for the info. does it help if i add the original receipt in there as well?
