"Bone spurs" is a non-specific term, it can refer to arthritic changes around the joints of the midfoot/forefoot with abnormal bone build-up at the top of the foot, typically in older individuals.
More commonly, and with Trump, it refers to bone production at the insertion of the plantar fascia or Achilles tendon on the calcaneus caused by repetitive tugging. The spurring is more a secondary consequence rather than the cause of pain, which arises from repeated micro-tearing and inflammation in the involved ligaments. These spurs are properly called enthesophytes, as opposed to osteophytes described in the second paragraph. In either case, they are generally not visible on direct examination, requiring radiographic imaging to evaluate.
