The shoe component may include a UV curable microlattice structure with a plurality of regions such that each region has a different density. In some cases, the microlattice structure may include a high density microlattice structure, a mid-level density microlattice structure, and a non-structural region with a low density microlattice structure. ## Claims ### Claim 1 A sports shoe comprising: an ultra-violet curable microlattice structure; a second material comprising a knit fabric; and a transition between the ultra-violet curable microlattice structure and the second material, the transition comprising: a transition zone in which the ultra-violet curable microlattice structure and the second material are arranged end to end; a bottom layer covering a bottom side of the transition zone and overlapping at least a portion of both the ultra-violet curable microlattice structure and the second material; and a top layer covering a top side of the transition zone and overlapping at least a portion of both the ultra-violet curable microlattice structure and the second material. ### Claim 2 (depends on 1) The sports shoe of claim 1, wherein at least a portion of the top layer is incorporated into an upper of the sports shoe. ### Claim 3 (depends on 2) The sports shoe of claim 2, wherein at least a portion of the top layer is incorporated into a vamp of the sports shoe. ### Claim 4 (depends on 2) The sports shoe of claim 2, wherein at least a portion of the top layer is incorporated into a rear portion of the upper of the sports shoe. ### Claim 5 (depends on 1) The sports shoe of claim 1, wherein the ultra-violet curable microlattice structure is arranged in a first area of the shoe configured for breathability and permeability and the second material is arranged in second area of the shoe configured for rigidity and support. ### Claim 6 (depends on 1) The sports shoe of claim 1, wherein the transition comprises (i) at least one first stitch that passes through the ultra-violet curable microlattice structure and at least one of the top layer or the bottom layer, and (ii) at least one second stitch that passes through the second material and at least one of the top layer or the bottom layer. ### Claim 7 A sports shoe comprising: an ultra-violet curable microlattice structure; a second material comprising a woven fabric; and a transition between the ultra-violet curable microlattice structure and the second material, the transition comprising: a transition zone in which the ultra-violet curable microlattice structure and the second material are arranged end to end; a bottom layer covering a bottom side of the transition zone and overlapping at least a portion of both the ultra-violet curable microlattice structure and the second material; and a top layer covering a top side of the transition zone and overlapping at least a portion of both the ultra-violet curable microlattice structure and the second material. ### Claim 8 (depends on 7) The sports shoe of claim 7, wherein at least a portion of the top layer is incorporated into an upper of the sports shoe. ### Claim 9 (depends on 8) The sports shoe of claim 8, wherein at least a portion of the top layer is incorporated into a vamp of the sports shoe. ### Claim 10 (depends on 8) The sports shoe of claim 8, wherein at least a portion of the top layer is incorporated into a rear portion of the upper of the sports shoe. ### Claim 11 (depends on 7) The sports shoe of claim 7, wherein the ultra-violet curable microlattice structure is arranged in a first area of the shoe configured for breathability and permeability and the second material is arranged in second area of the shoe configured for rigidity and support. ### Claim 12 (depends on 7) The sports shoe of claim 7, wherein the transition comprises (i) at least one first stitch that passes through the ultra-violet curable microlattice structure and at least one of the top layer or the bottom layer, and (ii) at least one second stitch that passes through the second material and at least one of the top layer or the bottom layer. ### Claim 13 A sports shoe comprising: an ultra-violet curable microlattice structure; a second material comprising non-woven fabric, leather, or synthetic leather; and a transition between the ultra-violet curable microlattice structure and the second material, the transition comprising: a transition zone in which the ultra-violet curable microlattice structure and the second material are arranged end to end; a bottom layer covering a bottom side of the transition zone and overlapping at least a portion of both the ultra-violet curable microlattice structure and the second material; and a top layer covering a top side of the transition zone and overlapping at least a portion of both the ultra-violet curable microlattice structure and the second material. ### Claim 14 (depends on 13) The sports shoe of claim 13, wherein at least a portion of the top layer is incorporated into an upper of the sports shoe. ### Claim 15 (depends on 14) The sports shoe of claim 14, wherein at least a portion of the top layer is incorporated into a vamp of the sports shoe. ### Claim 16 (depends on 14) The sports shoe of claim 14, wherein at least a portion of the top layer is incorporated into a rear portion of the upper of the sports shoe. ### Claim 17 (depends on 13) The sports shoe of claim 13, wherein the ultra-violet curable microlattice structure is arranged in a first area of the shoe configured for breathability and permeability and the second material is arranged in second area of the shoe configured for rigidity and support. ### Claim 18 (depends on 13) The sports shoe of claim 13, wherein the transition comprises (i) at least one first stitch that passes through the ultra-violet curable microlattice structure and at least one of the top layer or the bottom layer, and (ii) at least one second stitch that passes through the second material and at least one of the top layer or the bottom layer. ### Claim 19 (depends on 13) The sports shoe of claim 13, wherein the second material comprises non-woven fabric. ### Claim 20 (depends on 13) The sports shoe of claim 13, wherein the second material comprises leather or synthetic leather.
