An article of footwear comprising: a sole structure; an upper fixedly attached to the sole structure at a bite line disposed between the upper and the sole structure, the upper comprising: a lateral sidewall portion, a medial sidewall portion, and a vamp, the lateral sidewall portion and the medial sidewall portion cooperating to define an interior volume therebetween; an ankle opening operative to allow a wearer to extend a foot into the interior volume; a throat opening extending from the ankle opening toward the vamp and between the lateral sidewall portion and the medial sidewall portion; a closure mechanism configured to adjust the maximum size of the ankle opening, the closure mechanism comprising: a tongue having a first tongue portion attached to the vamp, a tongue distal edge, and a tongue body extending from the first tongue portion to the tongue distal edge; an adjustable lace having a lace first end and a lace second end that is operatively coupled to the lace first end at a pull tab, the adjustable lace being slidably coupled to each of the lateral sidewall portion and the medial sidewall portion between the lace first end and the lace second end, such that the adjustable lace operatively connects the lateral sidewall portion and the medial sidewall portion along the throat opening; a toggle coupled to and moveable along the adjustable lace between a first position on the adjustable lace and a second position on the adjustable lace, the toggle being fixedly attached to the tongue body; a tether fixed to the tongue distal edge at a first tether attachment point and fixed to the toggle at a second tether attachment point; and wherein moving the toggle from the first position on the adjustable lace to the second position on the adjustable lace operatively reduces the maximum size of the ankle opening, and wherein moving the toggle from the second position on the adjustable lace to the first position on the adjustable lace operatively increases the maximum size of the ankle opening. a sole structure;
