Yes every time i have received them in a bag the shoes have been fine and the box is usually messed up - destoryed ... BUT the point is
In those bags the only protecting your shoes is the shoe box, which is going to get beat in the shipping process. Once the shoes come out of the box, anything can happen. Ive had some bags be partially ripped from something in the shipping process. Or say it bangs up against stuff, the drives doesnt give a ---- and just tosses the bag or something. A scuff can easily come from the concrete. Some type of liquid could seem thru hole in the bag and ruin the shoe, vs going thru 2 boxes to mess up the shoes.
All kinds of things could happen in either scenario but its so much better being double boxed. They have no logical reasoning for not double boxing because they do it all the time without having to pay for "gift box". Like I said earlier my QS Lavas came double boxed from them, as well as my Jerry Rice Frees. The bag is just lazy and unacceptable
