The main symptom experienced due to Morton's toe is discomfort and callusing of the second metatarsal head.

Likewise the dryness and pronounced callusing of fingers and toes that I had already noticed.

The parietal callusing is weakly to strongly developed, especially posteriorly, and is absent in type species.

It's hard to know, just yet, whether for each of us this witnessing has caused an erosion or a sedimentation, a stripping away of the skin or a callusing.
