a support comprising cement, the support disposed in the bore of the housing and disposed in the internal cavity of the shell about the first conduit, the support holding the external snap-in feature of the outer rim engaged with the internal snap-in feature of the housing; and

a valve supported by the support in the bore of the housing, the valve disposed in communication between the first end of the housing and the first conduit.

2. The float shoe of claim 1 , wherein the first material comprises a metallic material, and wherein the second material comprises a composite material.

3. The float shoe of claim 1 , wherein the shell comprises an outer wall extending from the open proximal end to the enclosed distal end, the outer wall disposed circumferentially about the first conduit and defining the internal cavity therebetween, the internal cavity filled with the cement of the support, the first conduit communicating the valve at the open proximal end of the shell with the distal outlet at the enclosed distal end of the shell.

4. The float shoe of claim 3 , wherein the outer wall of the shell converges eccentrically from the open proximal end to the enclosed distal end of the shell.

5. The float shoe of claim 1 , wherein the first conduit extends cylindrically from the open proximal end to the enclosed distal end of the shell.

6. The float shoe of claim 1 , wherein the enclosed distal end of the shell encloses around the distal outlet.

7. The float shoe of claim 3 , further comprising a second conduit disposed in the internal cavity and communicating the first conduit with a port defined in the outer wall of the shell.

8. The float shoe of claim 1 , wherein the first conduit comprises a separate component of the nose connected to the enclosed distal end of the shell and left in place with the cement in the internal cavity.

9. The float shoe of claim 1 , wherein the first conduit comprises a passageway left in place in the cement after removal of a separate component of the nose.

10. The float shoe of claim 1 , wherein the first conduit comprises an integral component of the nose connected to the enclosed distal end of the shell and surrounded with the cement in the internal cavity.

11. The float shoe of claim 1 , wherein the internal snap-in feature comprises a lip disposed circumferentially about an inside surface of the bore; and wherein the external snap-in feature comprises a slot defined circumferentially about an external surface of the outer rim.

12. The float shoe of claim 1 , wherein the internal and external snap-in features are selected from the group consisting of a lip, a slot, an indentation, a tooth, a ratchet, a thread, a detent, a shoulder, and a catch.

13. A method of manufacturing a float shoe for a downhole tubular, the method comprising not necessarily in sequence:

positioning a valve in a bore of a housing for the float shoe having first and second ends, the first end configured to attach to the downhole tubular, the bore having an internal snap-in feature disposed on the bore;

extending the second end of the housing with a nose by attaching an external snap-in feature disposed on an outer rim of an open proximal end of a shell to the internal snap-in feature toward the second end of the housing, the shell having an enclosed distal end enclosing an internal cavity communicating with the bore;

filling an annular space around the valve with cement to support the valve disposed in the bore of the housing;

supporting the attachment of the external snap-in feature of the outer rim inside the internal snap-in feature of the housing after attaching the external snap-in feature to the internal snap-in feature by at least filling the internal cavity of the shell inside the open proximal end with cement; and

communicating the valve with a distal outlet of the nose by connecting a first conduit in the nose to the enclosed distal end of the shell and extending the first conduit into the internal cavity to be surrounded by the filled cement.

14. The method of claim 13 , wherein filling the annular space and the internal cavity with the cement and attaching the external snap-in feature of the shell to the internal snap-in feature of the housing comprises:

filling at least a portion of the internal cavity of the shell with the cement before attaching the shell to the second end,

attaching the shell to the second end, and

filling a remaining portion of the internal cavity to support the attachment of the external snap-in feature inside the internal snap-in feature and filling the annular space around the valve with the cement to support the valve disposed in the bore of the housing, after attaching the shell to the second end.

15. The method of claim 13 , wherein filling the annular space and the internal cavity with the cement and attaching the external snap-in feature of the shell to the internal snap-in feature of the housing comprises:

attaching the external snap-in feature of the shell to the internal snap-in feature of the housing,

filling the internal cavity of the shell with the cement to support the attachment of the external snap-in feature inside the internal snap-in feature after attaching the shell to the housing, and

filling the annular space around the valve with the cement to support the valve disposed in the bore of the housing.

16. The method of claim 13 , wherein connecting the first conduit in the nose to the enclosed distal end of the shell and extending the first conduit into the internal cavity to be surrounded by the filled cement comprises positioning a separate component of the nose connected to the enclosed distal end of the shell, filling the internal cavity of the shell with the cement around the separate component, and

(a) leaving the separate component in place as the first conduit after filling the internal cavity of the shell with the cement; or

(b) removing the separate component to leave a passageway in place as the first conduit after filling the internal cavity of the shell with cement.

17. The method of claim 13 , wherein connecting the first conduit in the nose to the enclosed distal end of the shell and extending the first conduit into the internal cavity to be surrounded by the filled cement comprises forming an integral component of the nose connected to the enclosed distal end of the shell and filling the internal cavity of the shell with the cement around the integral component as the first conduit.

18. The method of claim 13 , wherein the internal snap-in feature comprises a lip disposed circumferentially about an inside surface of the bore; and wherein the external snap-in feature comprises a slot defined circumferentially about an external surface of the outer rim.

19. The method of claim 13 , wherein the internal and external snap-in features are selected from the group consisting of a lip, a slot, an indentation, a tooth, a ratchet, a thread, a detent, a shoulder, and a catch.
