Abstract
Articles of footwear may include selectively engageable traction elements that engage with a surface or the ground during certain activities and do not engage with the surface or the ground during other activities. The selectively engageable traction elements are caused to engage with the ground or surface when a portion of the footwear is flexed. When the footwear is in its unflexed position, the selectively engageable traction elements may not engage with the ground or surface. Selectively engageable traction elements may be desired or may be useful during particular, targeted movements such as sharp turns, pivoting, sudden or abrupt starting and stopping motions, and the like and in changing environmental conditions, such as on various surfaces having different characteristics. Wearers of such footwear may benefit from the extra traction provided by the selectively engageable traction elements when performing the targeted movements and/or when wearing the footwear on surfaces with varying conditions.
