摘要
A shoe may include a sole and an upper. The upper may have a medial side and a lateral side that each have an edge positioned on opposing side of the shoe's tongue. The upper's medial side and/or the upper's lateral side may include stiffened regions and flexible regions with each stiffened region being disposed between two flexible regions so that the stiffened regions are moveable relative to one another upon tensioning of the medial and lateral sides of the upper. The opposing edges of the upper's medial and lateral sides may be substantially linear or straight prior to tensioning of the upper's medial and lateral sides and may be substantially uneven or nonlinear subsequent to tensioning of the upper's medial and lateral sides due to relative movement of the stiffened regions.
