You do have to be careful of a lot of the overseas sites. But I have ordered from Air-Knight twice now and the shoes are 100% authentic and everything was smooth sailing with them.
Ok before you start "snitching" on them get your facts straight. There is NO release date for GS, PS, or infant hornets. That store is doing nothing wrong, and is just following the e-mail that every store got today saying to put them out.
