an insert body forming a part of the sole in an installed position; and

an insert channel oriented toward the interior cavity of the body.

2 . The golf club head of claim 1 , wherein a slot width of the leading edge slot is greater than a slot depth of the leading edge slot.

3 . The golf club head of claim 1 , wherein the leading edge slot comprises a rear slot wall extending vertically upward from the sole, and wherein the leading edge insert comprises a retaining component to help secure the leading edge insert to the leading edge slot.

4 . The golf club head of claim 3 , wherein the leading edge slot comprises a rib extending from an interior surface of the sole to the rear slot wall.

5 . A golf club head comprising:

a body comprising:

a leading edge defined as a boundary between the face and the sole;

a leading edge slot rearward of the face, wherein the leading edge slot is within 1.0 mm of the face;

a central region rearward of the leading edge slot; and

a trailing edge rearward of the central region; and

a leading edge insert to fit into the leading edge slot, wherein the leading edge insert comprises:

an insert body forming a part of the sole in an installed position; and

an insert channel oriented toward an interior cavity of the body.

6 . The golf club head of claim 5 , wherein the leading edge slot is located immediately rearward of the leading edge.

7 . The golf club head of claim 5 , wherein an insert width of the leading edge insert is greater than an insert depth of the leading edge insert.

a face;

a back extending rearward from at least a part of the face; and

a sole, wherein the sole comprises:

a leading edge slot rearward of the face; and

a leading edge insert to fit into the leading edge slot, wherein the leading edge insert comprises:

an insert body comprising a first material, wherein a bottom of the insert body forms a part of the sole in an installed position;

a central layer comprising a second material different from the first material, wherein the central layer is positioned above the insert body; and

a top layer comprising the first material, wherein the top layer is positioned above the central layer.

13 . The golf club head of claim 12 , wherein the first material comprises a polymer, and wherein the second material comprises a metal.

14 . The golf club head of claim 12 , wherein the insert body comprises first supporting members, wherein the central layer comprises second supporting members, wherein the top layer comprises third supporting members, and wherein the first supporting members, the second supporting members, and the third supporting members comprise a first material.

15 . The golf club head of claim 12 , wherein the leading edge insert further comprises an insert channel oriented toward an interior cavity of the body.
