First Claim
1. A sole structure, comprising:
- a sole base member; and
a self-adjustinq stud, wherein the self-adjustinq stud is attached to the sole base member, and wherein the self-adjusting stud comprisesa metal first portion having a first compressibility; and
a second portion having a second compressibility that is greater than the first compressibility, wherein the second portion surrounds the first portion,wherein the first portion and the second portion are substantially uncompressed when the self-adjusting stud comes into contact with a surface of a first hardness and the first portion is substantially uncompressed and the second portion is compressed when the self-adjusting stud comes into contact with a surface of a second hardness, and wherein the first hardness is less than the second hardness, andwherein the second portion includes a two plate structure comprising a first plate and a second plate that are spaced apart such that when a force is applied to the first plate, the space between the first plate and the second plate is decreased.

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.

7. A sole structure, comprising:
-
a sole base member; and a self-adjusting stud, wherein the self-adjusting stud is attached to the sole base member and comprises a stud body having a hole extending through a center region thereof; and a metal pin extending through the hole in the stud body, wherein at least a portion of the stud body and a tip of the pin form a ground-contact surface of the self-adjusting stud, wherein the stud body is in a first, extended position when the self-adjusting stud contacts a surface having a first hardness and the stud body is in a second, retracted position when the self-adjusting stud contacts a surface having a second hardness that is greater than the first hardness, wherein the stud body includes a two-plate structure comprising a first plate and a second plate, and a space defined therebetween, wherein the space between the first plate and the second plate is a first distance when the stud body is in the first, extended position and the space between the first plate and the second plate is a second distance when the stud body is in the second, retracted position, and wherein the first distance is greater than the second distance. - View Dependent Claims (8, 9, 11)
