Abstract: Article of footwear comprised of an upper that includes a vamp, the vamp including a first wall, at least two keepers configured to receive a portion of a lace, each keeper being arranged on either side of a sagittal plane of the article of footwear. Each loop is defined by the following: the interstitial space between the first wall and a yoke locally covering an outer surface of the first wall, the interstitial space having an anterior opening and a posterior opening through which a portion of the lace extends, and an upper linkage between the first wall and the yoke, the upper linkage being achieved due to a first affixer located in a first connection zone close to the sagittal plane, whereby the yoke is superimposed on the first wall without folding.
