1. An adjustable tensioning device comprising:
a rotatable dial, wherein rotating the rotatable dial causes a spool to turn and a tensioning element to wind around the spool, wherein the spool is configured to store four or more inches of the tensioning element;
a torque multiplying system that increases the force applied to the tensioning element wound around the spool, wherein the torque multiplying system is capable of increasing the force applied to the tensioning element by three times or more;
an anti-unspooling mechanism to prevent the tensioning element from unwinding from the spool when a tension acting on the spool is 50 pounds or more; and
a clutch that couples and decouples the rotatable dial from the spool;
wherein the clutch comprises two elements, a first clutch element comprising a plurality of protrusions, and a second clutch element comprising a plurality of recesses, wherein the plurality of protrusions of the first clutch element intermesh with the plurality of recesses of the second clutch element, wherein the plurality of protrusions have protrusion faces, and wherein the protrusion faces are configured to substantially align with an axial motion of the first clutch element in relation to the second clutch element.
