The article of footwear also includes a tightening grip operable to be moved away from the upper in a first direction to move the first cable in the tightening direction and a cable lock operable in a locked state to restrict movement of the first cable in the loosening direction and operable in an unlocked state to permit movement of the first cable in the loosening direction. A release grip is operable to be moved away from the upper in a second direction to move the cable lock from the locked state to the unlocked state, whereby the release grip is separate from the tightening grip. ## Claims ### Claim 1 A cable lock mechanism comprising: a housing defining a cavity; a first cable having a first portion and a second portion; a second cable having a first portion and a second portion; a unitary spool disposed within the cavity and including a first annular groove receiving the first cable and a second annular groove receiving the second cable, the spool rotatable in a first direction relative to the housing to unwind the first cable from the housing and wind the second cable within the second annular groove and rotatable in a second direction relative to the housing to unwind the second cable from the housing and wind the first cable within the first annular groove; and a first lock pawl supported by the housing and operable between a locked state restricting rotation of the spool relative to the housing in the second direction and an unlocked state permitting rotation of the spool relative to the housing in the second direction. ### Claim 2 (depends on 1) The cable lock mechanism of claim 1, wherein the spool is rotatable in the first direction to payout the first portion and the second portion of the first cable and to spool the first portion and the second portion of the second cable. ### Claim 3 (depends on 2) The cable lock mechanism of claim 2, wherein the spool is rotatable in the second direction to payout the first portion and the second portion of the second cable and to spool the first portion and the second portion of the first cable. ### Claim 4 (depends on 1) The cable lock mechanism of claim 1, wherein a length of the first portion of the first cable is equal to a length of the first portion of the second cable. ### Claim 5 (depends on 1) The cable lock mechanism of claim 1, wherein a length of the second portion of the first cable is equal to a length of the second portion of the second cable. ### Claim 6 (depends on 1) The cable lock mechanism of claim 1, wherein the first lock pawl permits rotation of the spool relative to the housing in the first direction when in the locked state. ### Claim 7 (depends on 1) The cable lock mechanism of claim 1, wherein the first lock pawl includes a series of first teeth that engage the spool in the locked state. ### Claim 8 (depends on 7) The cable lock mechanism of claim 7, wherein the spool includes a series of second teeth that matingly receive the series of first teeth when the first lock pawl is in the locked state. ### Claim 9 (depends on 8) The cable lock mechanism of claim 8, wherein the series of second teeth are formed on an inner surface of the spool. ### Claim 10 (depends on 1) The cable lock mechanism of claim 1, wherein the first lock pawl is pivotably supported within the cavity by the housing. ### Claim 11 (depends on 1) The cable lock mechanism of claim 1, wherein the first lock pawl is biased into the locked state by a biasing spring. ### Claim 12 (depends on 1) The cable lock mechanism of claim 1, further comprising a second lock pawl pivotably supported within the housing between a first position spaced apart from the spool and a second position in contact with a control surface of the spool. ### Claim 13 (depends on 12) The cable lock mechanism of claim 12, wherein the second lock pawl is pivotably supported by one of the housing and the first lock pawl. ### Claim 14 (depends on 12) The cable lock mechanism of claim 12, wherein the second lock pawl is biased into the second position. ### Claim 15 (depends on 12) The cable lock mechanism of claim 12, wherein the second lock pawl is biased into the second position by a biasing spring.
