1. A wearable device configured to selectively provide roller transportation, comprising: a shoe; a plurality of wheel assemblies, each wheel assembly being configured to selectively roll relative to a ground surface about an associated axis of rotation; and a frame connected between the wheel assemblies, the frame comprising a trunk and a plurality of branches extending from the trunk, the trunk comprising a trunk midline plane that is substantially orthogonal to the ground surface, the trunk extending generally along a forward-rearward direction of the wearable device, wherein each of the branches are configured for connection to at least one of the plurality of wheel assemblies, wherein each of the branches comprise a branch midline plane that intersects the trunk midline plane at an outer angle, wherein at least two of the plurality of branches extend generally leftward from the trunk midline plane and at least two of the plurality of branches extend generally rightward from the trunk midline plane, and wherein each of the branches, as viewed from above, comprise a branch endpoint coincident with each of (1) the respective branch midline plane and (2) the respective axis of rotation; wherein at least a portion of the shoe is located vertically higher than at least a portion of the frame when at least one of the wheel assemblies is in contact with the ground surface and the at least one of the wheel assemblies is positioned to selectively roll relative to the ground surface; and wherein at least one of the branch endpoints is misaligned relative to the other branch endpoints in both (1) a forward-rearward direction and (2) a leftward-rightward direction. 2. The wearable device according to claim 1, wherein at least a portion of the frame is embedded within the shoe. 3. The wearable device according to claim 1, wherein the outer angles associated with at least two of the branches are unequal in value. 4. The wearable device according to claim 1 further comprising: four branches, each of the four branches comprising a different length and each of the branches comprising a branch midline plane intersecting the trunk midline plane with different outer angle values, wherein the respective branch lengths are measured, as viewed from above, from the trunk midline plane to the respective branch endpoints along the respective branch midline planes. 5. The wearable device according to claim 1, wherein the trunk vertically extends between a clearance plane coincident with a lowest portion of the frame and an upper interface surface of the frame that contacts the shoe in a vertically highest location. 6. The wearable device according to claim 5, wherein the trunk comprises the lowest portion of the frame. 7. The wearable device according to claim 5, wherein a branch comprises the lowest portion of the frame. 8. The wearable device according to claim 5, wherein the trunk comprises the upper interface surface. 9. The wearable device according to claim 5, wherein the upper interface surface is at least partially received within the shoe. 10. The wearable device according to claim 5, wherein the upper interface surface is at least partially received within a sole cutout profile of the shoe. 11. The wearable device according to claim 1, wherein each of the branches comprises a suspension block extending in a substantially vertical direction from the associated branch. 12. The wearable device according to claim 11, wherein each of the suspension blocks comprises a suspension cavity for receiving at least a portion of a suspension. 13. The wearable device according to claim 12, wherein each of the suspension cavities comprises a cavity axis that extends in a generally leftward-rightward direction of the wearable device. 14. The wearable device according to claim 13, wherein at least two branches and at least two associated cavity axes are associated with a front sole of the shoe and wherein at least two branches and at least two associated cavity axes are associated with a rear sole of the shoe. 15. The wearable device according to claim 13, wherein the wheel assemblies associated with the two branches associated with the rear sole of the shoe are separated in a leftward-rightward direction of the wearable device by a distance less than a distance that that the wheel assemblies associated with the two branches associated with the front sole of the shoe are separated in the leftward-rightward direction of the wearable device. 16. The wearable device according to claim 13: wherein the wheel assembly associated with a front-left branch is offset in a frontward-rearward direction of the wearable device relative to the wheel assembly associated with a front-right branch;wherein the wheel assembly associated with a rear-left branch is offset in the frontward-rearward direction of the wearable device relative to the wheel assembly associated with a rear-right branch;wherein the wheel assembly associated with the front-left branch is offset in a leftward-rightward direction of the wearable device relative to the wheel assembly associated with the rear-left branch; andwherein the wheel assembly associated with a front-right branch is offset in the leftward-rightward direction of the wearable device relative to the wheel assembly associated with the rear-right branch. 17. The wearable device according to claim 1, wherein at least one of the branches are adjustable in length.
