Abstract
An article of footwear with a size-adjustable system capable of adjusting the size of the artifice of footwear is provided. The size-adjustable system comprises three sets of removable inserts. The inserts engage the article of footwear in the heel region of the upper to provide both space-filling in the heel region as well as stabilization of the foot. When each set of sizing inserts are disposed within the article of footwear, the size of the foot the article of footwear is capable of receiving is different. By providing a size-adjustable system, the article of footwear is capable of receiving multiple foot sizes, such as that of a growing child.
