Abstract
An article of footwear that includes a sizing system to allow the shoe size to be adjustable by the wearer. The article of footwear in the form of a shoe includes a sole, an upper extending from the sole, and a sizing member located within the upper, in which the sizing member is attached to the upper at the rear end of the athletic shoe. The sizing member includes an inner core, a separation feature, a fastening system, and locking feature. The inner core is substantially enclosed in a lining and the separation feature includes a plurality of perforations at the top of the sizing member. The sizing member enables a user to adjust the effective length of the shoe. The article of footwear may also include separable sockliner layers. This enables a user to adjust the effective height of the shoe. If an upper sockliner layer wraps upwardly at its sides and/or if the sizing member wraps substantially around the heel, removal of the upper sockliner layer 51 and/or the sizing element enables a user to adjust the effective width of the shoe. Also a method of adjusting the size of the article of footwear is disclosed.
