wherein an internal surface of the body forms at least one ring projecting towards the body axis, the internal surface defining a generally continuous even surface outside the at least one ring;

wherein the at least one peripheral profile portion and the at least one ring are formed independently from one another, and from the thickness of the body.

2. The orthotic or prosthetic sleeve according to claim 1 , wherein the at least one peripheral portion defines a plurality of annular projections extending radially outwardly from and about the body axis.

3. The orthotic or prosthetic sleeve according to claim 2 , wherein the plurality of projections are generally uniformly spaced from one another.

4. The orthotic or prosthetic sleeve according to claim 1 , wherein the at least one peripheral portion defines a plurality of projections extending longitudinally along the body about the circumference thereof.

5. The orthotic or prosthetic sleeve according to claim 4 , wherein the plurality of projections are generally uniformly spaced from one another.

6. The orthotic or prosthetic sleeve according to claim 1 , wherein the at least one peripheral portion defines a plurality of annular projections extending obliquely relative to the body axis.

7. The orthotic or prosthetic sleeve according to claim 1 , wherein the at least one peripheral portion is located within only at least one of the proximal and center portions of the body.

8. The orthotic or prosthetic sleeve according to claim 1 , wherein the body tapers in diameter from at least the boundary between the center portion and the distal portion, to a distal end of the distal portion.

9. The orthotic or prosthetic sleeve according to claim 1 , wherein the at least one peripheral profile portion includes a first plurality of annular projections extending radially outwardly from the body axis and located within the center portion of the body, and a second plurality of longitudinal projections extending longitudinally along the body about the circumference thereof and located within the proximal portion of the body.

10. The orthotic or prosthetic sleeve according to claim 1 , wherein the at least one ring includes a first ring located within the proximal portion of the body, and a second ring located within the distal portion of the body.

11. An elasticized sleeve having internal and external surfaces, comprising:

a tubular shaped body, open at both ends, extending along an axis, and formed of an elasticized fabric layer and an elastomer polymeric layer that is discretely secured to the fabric layer, the body having a distal portion, a proximal portion, and a center portion extending between the distal and proximal portions, the elasticized fabric defining the external surface of the body;

wherein an internal surface of the tubular sleeve is entirely coated with the elastomer polymeric layer that defines the internal surface of the body, the elasticized fabric layer being secured to the elastomer polymeric layer and coextensive therewith;

wherein an external surface of the body defines at least one peripheral profile portion having an undulating solid wall thickness;

wherein the elastomer polymeric layer forms at least two rings of solid wall thickness defined along the internal surface of the body, and the at least two rings projecting towards the body axis;

wherein the at least one peripheral profile portion and the at least two rings are formed independently from one another; and

wherein the at least two rings includes a first ring located within the proximal portion of the body, and a second ring located within the distal portion of the body.

12. The elasticized sleeve according to claim 11 , wherein the elasticized fabric layer has a higher stiffness along one direction than along a direction that is orthogonal relative to the one direction.

13. The elasticized sleeve according to claim 11 , wherein the at least one peripheral profile portion defines a plurality of annular projections extending radially outwardly from the body axis.

14. The elasticized sleeve according to claim 13 , wherein the plurality of projections are generally uniformly spaced from one another.

15. The elasticized sleeve according to claim 13 , wherein the plurality of projections are variably spaced from one another.

16. The elasticized sleeve according to claim 11 , wherein the at least one peripheral profile portion defines a plurality of longitudinal projections extending longitudinally along the body about the circumference thereof.

17. The elasticized sleeve according to claim 16 , wherein the plurality of projections are generally uniformly spaced from one another.

18. The elasticized sleeve according to claim 11 , wherein the body tapers in diameter from at least the boundary between the center portion and the distal portion, to the distal end of the distal portion.

19. The elasticized sleeve according to claim 11 , wherein the at least one peripheral profile portion includes a first plurality of annular projections extending radially outwardly from the body axis and located within the center portion of the body, and a second plurality of longitudinal projections extending longitudinally along the body about the circumference thereof and located within the proximal portion of the body.
