You can find it at DHGate or Sellerkey but being extremely careful is right. When you look around for such merchandise, make sure you get it only from powersellers- NEVER trust the new people if it can be helped.
Policy is effectively in place to make sure you use communication directly to your seller, inform sellerkey/DHGate you are paying directly by Paypal, so that if any issues arise it can be cancelled.
escrow makes sure the party is not paid until all issues are satisfied.
But another, much less intensive alternative is to use liquidation.com and buy up a liquidated over-stock set of shoes. Many times they are just given away. But pick a really good batch as that too has problems!
And there are other very good suppliers that do carry clothing. Aceclothing.net is one. ETSY.com gets quite a few as well.
