First Claim
1. An article of footwear comprising:
- a sole structure; and
a self-adjusting stud, the self-adjusting stud including a static cleat and an extendable element, and whereinthe static cleat extends downward from a bottom surface of the sole structure,the static cleat has a hole defined therein, the hole having an opening on a bottom of the static cleat,the extendable element includes a shaft and a leaf spring,the shaft extends through the static cleat hole, a lower end of the shaft protruding through the opening,the extendable element is movable between an extended position in which the static cleat and the extendable element have a first combined length and a retracted position in which the static cleat and the extendable element have a second combined length less than the first combined length, andthe leaf spring radiates outward from an upper end of the extendable element and biases the shaft to the retracted position.

Abstract
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.
