Several methods could produce this effect.

The simplest practical options are:

• Drop the shoe and use a very fast shutter speed with continuous/burst shooting to freeze it just before it hits the ground.
• Support the shoe with something hard to see, such as thin monofilament/fishing line or a hidden prop, then remove that support in post-processing.
• Make a composite from multiple frames, such as one clean background shot and another with the shoe positioned where wanted.

If the shoe is extremely sharp and perfectly placed, that often suggests either many burst frames were taken to catch the right instant, or some kind of setup/compositing was used for control. A thin line is especially plausible because it can be easy to retouch out, particularly against a simple or blurred background.

So yes, it could be done purely in-camera with timing and a fast shutter, but it could just as easily be a staged shot with post-processing. Without seeing behind-the-scenes details, you can’t know for certain from the final image alone.
