It is medically called crepitus.

In most cases, you shouldn’t worry if you experience ankle popping or ankle clicking. Again, synovial fluid is the most common reason why your ankles crack when walking. Your bones and ligaments don’t produce that sound, in most cases.

There are, however, some cases where ankle cracking is a sign that your ankles are weak or unstable. If this is the case, then your ankle will be more prone to injury, including sprains, fractures, or dislocation. If you’ve been diagnosed with weak ankles, you should try to avoid ankle cracking whenever possible. Specifically, you should keep from rotating your ankle so that it cracks. This will help reduce the chances that the joints will be injured in the long run.
