A second component including a second surface, and including the other of the channel and the projection disposed on an opposite side of the second component than the second surface, the other slidably engaging the channel or the projection to selectively couple the first component and the second component together. One of the first surface and the second surface is operable to be attached to the prosthetic device, and the other is operable to be attached to a sole structure having a ground-engaging surface. ## Claims ### Claim 1 An attachment system for use with a prosthetic device, the attachment system comprising: a first component including a first surface, and further including one of a channel and a projection disposed on an opposite side of the first component than the first surface; and a second component including a second surface, and further including the other of the channel and the projection disposed on an opposite side of the second component than the second surface, the other of the channel and the projection slidably engaging the one of the channel and the projection to selectively couple the first component and the second component together; wherein one of the first surface and the second surface is operable to be attached to the prosthetic device and the other of the first surface and the second surface is operable to be attached to a sole structure having a ground-engaging surface. ### Claim 2 (depends on 1) The attachment system of claim 1, wherein the slidably engaging comprises the channel matingly receiving the projection therein. ### Claim 3 (depends on 1) The attachment system of claim 1, wherein the projection includes a first portion that is disposed at a junction of the prosthetic device and the one of the first surface and the second surface, and a second portion that is spaced apart from the first portion and is received by the channel, a cross-section of the projection being wider at the second portion than at the first portion. ### Claim 4 (depends on 3) The attachment system of claim 3, wherein the channel and the projection cooperate to selectively provide a dovetail connection between the first component and the second component. ### Claim 5 (depends on 1) The attachment system of claim 1, wherein the sole structure includes a cushioning layer disposed between the other of the first surface and the second surface and the ground-engaging surface. ### Claim 6 (depends on 5) The attachment system of claim 5, wherein the ground-engaging surface is formed by the cushioning layer. ### Claim 7 (depends on 5) The attachment system of claim 5, wherein the ground-engaging surface is formed by an outsole layer that is attached to the cushioning layer. ### Claim 8 (depends on 1) The attachment system of claim 1, further comprising a latch mechanism operable to fix a relative position between the first component and the second component. ### Claim 9 (depends on 8) The attachment system of claim 8, wherein the latch mechanism is automatically moved into a latched state to fix the relative position between the first component and the second component when the projection is moved into the channel a predetermined distance. ### Claim 10 (depends on 9) The attachment system of claim 9, wherein the latch mechanism includes a male component that is fixed for movement with one of the first component and the second component and a female component that is fixed for movement with the other of the first component and the second component, the female component receiving the male component and securing the male component to the female component when the projection is moved the predetermined distance into the channel. ### Claim 11 (depends on 8) The attachment system of claim 8, wherein the latch mechanism includes a latching element fixed for movement with one of the first component and the second component, and further including a latching feature fixed for movement with the other of the first component and the second component, the latching element operable to be actuated by and to engage the latching feature in response to a sliding engagement between the first component and the second component. ### Claim 12 (depends on 11) The attachment system of claim 11, wherein the other of the first component and the second component includes a ramping surface operable to deflect the latching element to position the latching element into engagement with the latching feature. ### Claim 13 (depends on 1) The attachment system of claim 1, wherein the prosthetic device is a foot prosthetic device. ### Claim 14 (depends on 13) The attachment system of claim 13, wherein the prosthetic device is a blade prosthetic device. ### Claim 15 (depends on 1) The attachment system of claim 1, wherein the first component and the second component are elongate components. ### Claim 16 An attachment system for use with a prosthetic device, the attachment system comprising: a first elongate component attached to the prosthetic device; and a second elongate component attached to a sole structure having a ground-engaging surface, the second elongate component slidably receiving the first elongate component to attach the sole structure to the prosthetic device. ### Claim 17 (depends on 16) The attachment system of claim 16, wherein the second elongate component matingly receives the first elongate component therein. ### Claim 18 (depends on 16) The attachment system of claim 16, wherein the first elongate component includes a projection extending from a surface of the prosthetic device, the projection including a first portion disposed at a junction of the projection and the surface of the prosthetic device and a second portion that is spaced apart from the first portion and is received by the second component. ### Claim 19 (depends on 18) The attachment system of claim 18, wherein a cross-section of the projection is wider at the second portion than at the first portion. ### Claim 20 (depends on 19) The attachment system of claim 19, wherein the second component includes a channel, the channel and the projection cooperating to selectively provide a dovetail connection between the first elongate component and the second elongate component. ### Claim 21 (depends on 16) The attachment system of claim 16, wherein the sole structure includes a cushioning layer disposed between the second elongate component and the ground-engaging surface. ### Claim 22 (depends on 21) The attachment system of claim 21, wherein the ground-engaging surface is formed by the cushioning layer. ### Claim 23 (depends on 21) The attachment system of claim 21, wherein the ground-engaging surface is formed by an outsole layer that is attached to the cushioning layer. ### Claim 24 (depends on 16) The attachment system of claim 16, further comprising a latch mechanism operable to selectively fix a relative position between the first elongate component and the second elongate component. ### Claim 25 (depends on 24) The attachment system of claim 24, wherein the latch mechanism is automatically moved into a latched state to fix the relative position between the first elongate component and the second elongate component when the first elongate component is slidably moved into the second elongate component a predetermined distance. ### Claim at position 26 26-54.
