Talon noir, also referred to as black heel or calcaneal petechia, is an asymptomatic discoloration of the acral skin due to hemorrhage caused by shear-force injuries. The lesions mostly appear on heals but can occur on the hand and other parts. Talon noir often occurs in athletes.

It usually does not require treatment and resolves spontaneously within four to six weeks. However, they may recur if the triggering skin trauma continues.
