A retention system for footwear can include opposed closure elements and a tensioner configured to urge the opposed closure elements toward each other in response to a tensile force applied to the tensioner. Opposed first and second anchors can be spaced from the tensioner. A retainer can have opposed first and second retainer couplers. The first retainer coupler can operatively engage the first anchor and the second retainer coupler can operatively engage the second anchor such that a tensile load applied to one or both of the first and second retainer couplers urges the retainer toward one or both of the first and second anchors. Each of the retainer couplers can be operatively engaged with the tensioner such that a tensile load applied to the tensioner urges the first retainer coupler and the second retainer coupler into tension and thereby urges the retainer toward one or both of the anchors.
