Holds one pair of running shoes, when placed inverted together, like in a shoe box.  This is shoe box sized.  It has an end handle, but no extra pockets inside or out.  If you gym bag has no extra pockets, this is a good way to store one pair of shoes and keeping them off your clothes.  It's not great as a stand alone bag because you cannot put a anything else in it...no room for much but shoes. Maybe a rolled up t-shirt.  It;'s well constructed and the zipper works well.  I like it.  I wish it was a tad bigger, though.  One would not be able to put high top athletic/basketball shoes in it, it's too tight.  Also, I wear a size nine and they fit well, and I can;t judge it, but it appears that a size 12+ shoe just plain might be too large for this bag.

It has a mesh side vent on one side, but not on the other, so it might get a tad rank if one left soggy shoes in it for very long.

I got black.
