A lace guide comprising: a middle section including an internal channel curved at a first radius and dimensioned to receive a lace cable (310, 430); a first extension extending from a first end of the middle section defining a first incoming lace axis along at least a portion of the internal channel extending through the first extension, the first extension configured to receive the lace cable (310, 430) through a lace reception opening opposite the first end of the middle section; and a second extension extending from a second end of the middle section defining a first outgoing lace axis along at least a portion of the internal channel extending through the second extension, the second extension configured to receive the lace cable (310, 430) from the middle section and route the lace cable (310, 430) through a lace exit opening along the first outgoing lace axis; wherein the lace guide is configured to define a first route for a lace cable (310, 430), the first route including receiving the lace cable (310, 430) along the first incoming lace axis and expelling the lace cable (310, 430) along the first outgoing lace axis; wherein the lace guide comprises a variable modulus of elasticity shifting from a high modulus at an apex to a low modulus towards the ends of the first and second extension; wherein the lace guide deflects, in response to tension on the lace cable (310, 430), resulting in defining a second route for the lace cable (310, 430), the second route including receiving the lace cable (310, 430) along a second incoming lace axis and expelling the lace cable (310, 430) along a second outgoing lace axis. a middle section including an internal channel curved at a first radius and dimensioned to receive a lace cable (310, 430); a first extension extending from a first end of the middle section defining a first incoming lace axis along at least a portion of the internal channel extending through the first extension, the first extension configured to receive the lace cable (310, 430) through a lace reception opening opposite the first end of the middle section; and a second extension extending from a second end of the middle section defining a first outgoing lace axis along at least a portion of the internal channel extending through the second extension, the second extension configured to receive the lace cable (310, 430) from the middle section and route the lace cable (310, 430) through a lace exit opening along the first outgoing lace axis; wherein the lace guide is configured to define a first route for a lace cable (310, 430), the first route including receiving the lace cable (310, 430) along the first incoming lace axis and expelling the lace cable (310, 430) along the first outgoing lace axis; wherein the lace guide comprises a variable modulus of elasticity shifting from a high modulus at an apex to a low modulus towards the ends of the first and second extension; wherein the lace guide deflects, in response to tension on the lace cable (310, 430), resulting in defining a second route for the lace cable (310, 430), the second route including receiving the lace cable (310, 430) along a second incoming lace axis and expelling the lace cable (310, 430) along a second outgoing lace axis.
