Articles of footwear may include self-adjusting studs that adjust to various types of conditions, environmental changes, and applied forces. The self-adjusting studs may have a first portion and a second portion of different levels of compressibilities and/or retractabilities that compress and extend based on the type of surface on which the wearer is walking or running. This footwear with self-adjusting studs may easily transition between surfaces of varying hardness without causing damage to the surface, but also providing the wearer with the necessary amount of traction on each type of surface. Wearers will enjoy the benefit of being able to move on various surfaces without the need to change their footwear multiple times to accommodate the wearer's varying traction needs on different surfaces.
