Disclosed is a footwear lacing system comprising a lace attached to a tightening mechanism. The lace extends through a series of guide members positioned along two opposing footwear closure portions. The lace and guides preferably have low friction surfaces to facilitate sliding of the lace along the guide members so that the lace evenly distributes tension across the footwear member. The tightening mechanism allows incremental adjustment of the tension of the lace. A release mechanism allows a user to quickly loosen the lace. A safety mechanism inhibits unintentional and/or accidental loosing of the lace.
