Sesamoids can be injured from blunt trauma, or overuse. Conventional footwear plays an important role in aggravating the sesamoids. Shoes with tapered toe boxes and toe spring cause the sesamoids to deviate from their aligned grooves, causing dysfunction.

When your Hallux, or big toe, is properly aligned with your first metatarsal bone, your sesamoids are also properly aligned and function as they’re intended to.
