Did you get it right?
Two modern shoe-storage details slipped into this old bowling alley.

The Answer
The correct answer is: the hook-and-loop shoe strap and the clear resealable zipper bag.
Here is why
- The rental shoe on the front counter closes with a wide hook-and-loop fabric strap.
- A pair of shoes in the upper-left cubbies sits inside a clear bag with a colored zipper track.
Why people miss it
