A sole includes an outer sole assembly including a plurality of outer sole members spaced apart from each other by a plurality of gaps. In addition, the sole includes a middle sole assembly defining a plurality of grooves, and an intermediate layer comprising an elastomer. The intermediate layer is disposed between the outer sole assembly and the middle sole assembly. The intermediate layer connects the middle sole assembly to the outer sole assembly. The intermediate layer is more elastic than each of the plurality of outer sole members. The intermediate layer is more elastic than the middle sole assembly. At least one of the gaps is vertically aligned with one of the grooves.

wherein the intermediate layer includes a continuous medial side and a plurality of fingers extending from the continuous medial side toward a lateral side of the sole.
2. The sole according to claim 1 , wherein the intermediate layer extends across at least one groove to separate the at least one groove from a vertically aligned gap.
3. The sole according to claim 1 , wherein the outer sole assembly further includes at least one connecting member that locally couples two adjacent outer sole members.
4. The sole according to claim 1 , wherein the intermediate layer is a TPU membrane, and one of the plurality of gaps is vertically aligned with a respective one of the plurality of grooves.
5. The sole according to claim 1 , wherein the intermediate layer has a different material composition than either the middle sole assembly or the outer sole assembly.
6. The sole according to claim 1 , wherein the sole is expandable along at least one of the plurality of gaps upon application of a downward force to the sole.
7. The sole according to claim 1 , wherein the intermediate layer is a unitary, one-piece structure.
8. The sole according to claim 1 , wherein the plurality of grooves do not extend through an entirety of a thickness of the middle sole assembly.
9. The sole according to claim 8 , wherein at least some of the plurality of gaps extend through an entirety of a thickness of the outer sole assembly.
10. The sole according to claim 1 , wherein the plurality of gaps includes a forward central gap that separates the sole between a lateral portion and a medial portion.
11. The sole according to claim 1 , wherein the outer sole assembly includes a base sole portion and a peripheral sole portion extending from the base sole portion.
12. The sole according to claim 11 , wherein the peripheral sole portion is configured to wrap up around a lower peripheral edge of an upper.
13. The sole according to claim 1 , wherein the plurality of outer sole members includes a forwardly disposed outer sole member, and the outer sole assembly includes a first tread pad and a second tread pad each coupled to the forwardly disposed outer sole member.
14. The sole according to claim 13 , wherein the plurality of gaps includes a peripheral gap partially disposed between the first tread pad and the second tread pad.
15. A sole, comprising:
an outer sole assembly including a plurality of outer sole members spaced apart from each other by a plurality of gaps;
a middle sole assembly defining a plurality of grooves; and
