The bladder system according to claim 1, wherein the valve member is disposed at a corner of the bladder; and wherein the inclined surface of the housing faces in a direction toward an interior portion of the bladder. 3. The bladder system according to claim 2, wherein the lower edge of the housing comprises a first arc extending from a first sidewall of the bladder at a first side of the corner to a second sidewall of the bladder on a second side of the corner opposite to the first side of the corner; and wherein the upper edge of the housing comprises a second arc extending from the first sidewall of the bladder to the second sidewall of the bladder. 4. The bladder system according to claim 1, wherein the housing of the valve member has a horizontal upper outer surface; and wherein a horizontal portion of the outer first surface of the lower layer is bonded to the horizontal upper outer surface of the housing of the valve member. 5. The bladder system according to claim 1, wherein the housing of the valve member has an upper outer surface at the upper edge and a lower outer surface at the lower edge; wherein the housing of the valve member has a first height from the lower outer surface to the upper outer surface;wherein the bladder, at an interior portion apart from the inclined portion of the lower layer, has a second height from the lower layer to the upper layer; andwherein the first height and the second height are substantially equal. 6. The bladder system according to claim 1, wherein the bladder has a forward wall, a sidewall, and a lower outer wall; wherein the housing has a forward outer surface, a side outer surface, and a lower outer surface;wherein the forward outer surface of the housing is approximately continuous with the forward wall of the bladder;wherein the side outer surface of the housing is approximately continuous with the sidewall of the bladder; andwherein the lower outer surface of the housing is approximately continuous with the lower outer wall of the bladder. 7. The bladder system according to claim 6, wherein the housing of the valve member has an upper outer surface; wherein the inclined surface, the forward outer surface, and the side outer surface join at the upper outer surface of the housing;wherein the outer first surface of the lower layer is attached to the upper outer surface of the housing;wherein the inner fourth surface of the upper layer is attached to the inner second surface of the lower layer over the upper outer surface of the housing; andwherein the upper layer extends substantially horizontally away from the valve member. 8. The bladder system according to claim 1, further comprising the article of footwear; wherein the article of footwear comprises an upper and an outsole;wherein the bladder is disposed between the upper and the outsole; andwherein the outer first surface of the lower layer is disposed against the outsole. 9. The bladder system according to claim 1, wherein the valve is configured to engage an external pump that supplies fluid to the valve. 10. The bladder system according to claim 1, further comprising a tensile member disposed inside the bladder; wherein a top layer of the tensile member is attached to the inner fourth surface of the upper layer; andwherein a bottom layer of the tensile member is attached to the inner second surface of the lower layer. 11. A method of making a bladder system, comprising: attaching an outer first surface of a lower layer to a valve member,wherein the valve member includes a housing, a valve, an outlet port, and a fluid passage,wherein the fluid passage provides fluid communication between the valve and the outlet port,wherein the housing has an upper edge, a lower edge, and an inclined surface extending from the lower edge to the upper edge,wherein the outlet port is disposed at the inclined surface,wherein an inclined portion of the lower layer is attached, at the outer first surface of the lower layer, to the inclined surface of the housing of the valve member, andwherein the lower layer has an inner second surface opposite to the outer first surface;forming an opening in the inclined portion of the lower layer,wherein the opening is aligned with the outlet port disposed at the inclined surface of the housing;attaching the inner second surface of the lower layer to an upper layer to form a bladder having an interior cavity,wherein the valve member is disposed outside of the interior cavity; andproviding fluid communication from the valve to the interior cavity through the fluid passage, the outlet port, and the opening in the inclined portion of the lower layer. 12. The method according to claim 11, wherein attaching the inner second surface of the lower layer to the upper layer comprises joining a first periphery of the lower layer with a second periphery of the upper layer. 13. The method according to claim 11, further comprising positioning the valve member at a corner of the bladder, with the inclined surface of the housing facing an interior portion of the bladder. 14. The method according to claim 13, wherein the lower edge of the housing comprises a first arc extending from a first sidewall of the bladder at a first side of the corner to a second sidewall of the bladder on a second side of the corner opposite to the first side of the corner; and wherein the upper edge of the housing comprises a second arc extending from the first sidewall of the bladder to the second sidewall of the bladder. 15. The method according to claim 11, wherein the housing of the valve member has a horizontal upper outer surface; and wherein the method further comprises attaching a horizontal portion of the outer first surface of the lower layer to the horizontal upper outer surface of the housing of the valve member. 16. The method according to claim 11, wherein the bladder has a forward wall, a sidewall, and a lower outer wall; wherein the housing has a forward outer surface, a side outer surface, an upper outer surface, and a lower outer surface;wherein the inclined surface, the forward outer surface, and the side outer surface join at the upper outer surface of the housing;wherein the forward outer surface of the housing is approximately continuous with the forward wall of the bladder;wherein the side outer surface of the housing is approximately continuous with the sidewall of the bladder;wherein the lower outer surface of the housing is approximately continuous with the lower outer wall of the bladder;wherein the outer first surface of the lower layer is attached to the upper outer surface of the housing;wherein the upper layer is attached to the lower layer over the upper outer surface of the housing; andwherein the upper layer extends substantially horizontally away from the valve member. 17. The method according to claim 11, wherein attaching the outer first surface of the lower layer to the valve member comprises overmolding the lower layer onto the inclined surface of the housing of the valve member. 18. The method according to claim 11, wherein following the attaching of the outer first surface of the lower layer to the valve member, the method further comprises: attaching the inner second surface of the lower layer to a bottom layer of a tensile member; andattaching a top layer of the tensile member to the upper layer of the bladder. 19. A bladder system for an article of footwear, comprising: a bladder bounding an interior cavity;wherein the bladder has a first layer and a second layer that each comprises a boundary surface that encloses the interior cavity;a valve member including a housing, a valve, an outlet port, and a fluid passage;wherein the fluid passage provides fluid communication between the valve and the outlet port;wherein the housing has an inclined side wall facing an interior portion of the bladder;wherein the outlet port of the housing is disposed at the inclined side wall;wherein an inclined portion of the first layer is bonded to the inclined side wall of the housing of the valve member;wherein the inclined portion of the first layer defines an opening aligned with the outlet port disposed at the inclined side wall of the housing;wherein the valve is configured to receive fluid from external to the valve member; andwherein the valve is in fluid communication with the interior cavity through the fluid passage, the outlet port, and the opening in the first layer. 20. The bladder system of claim 19, wherein the second layer is substantially horizontal; wherein the first layer comprises a substantially horizontal portion and the inclined portion; andwherein the inclined portion extends from the substantially horizontal portion to the second layer.
