An article of footwear includes a strap system having a medial strap, a lateral strap, and a heel strap. The medial strap extends from a proximal end to a distal end selectively attachable to the upper at the lateral side. The lateral strap extends from a proximal end to a distal end selectively attachable to the upper at the medial side. The heel strap has a proximal portion fixed at the heel region and a distal portion selectively attachable to the upper by a heel strap fastener. The strap fastener is operable to attach one of the distal end of the medial strap and the distal end of the lateral strap to the heel strap.
