A base (1) is provided for a ski boot (2) and comprises a one-piece sole (4) defining heel and toe portions (6, 7) that is adapted to be secured to one or more outsole elements (8, 9, 10). Preferably, toe and heel outsole elements (8, 9) are bonded to the toe and heel portions (6, 7) respectively to form a base (1) with a unitary construction. The sole (4) also has a fiber-reinforced composite structure wherein a majority of the fibers in at least a mid-section (7) of the sole (4) between the heel and toe portions (6, 7) are angled at an acute angle with respect to a longitudinal axis (L) of the sole (4). Preferably, the mid-section (7) of the sole covers a position anatomically beneath the location of the metatarsal bones and the plantar arch of a person wearing the ski boot and a majority of the fibers in this mid-section (7) of the sole are angled at substantially ±45°±10° to the longitudinal axis (L) of the sole (4) and between 5% and 10% of the fibers in the mid-section (7) of the sole (4) are substantially aligned with the longitudinal axis of the sole at angles within ±20° of being parallel to the longitudinal axis (L) of the sole (4). A ski boot (2) incorporating such a sole (4) is also provided.

1. A base for a ski boot comprising a one-piece sole defining heel and toe portions that is adapted to be secured to one or more outsole elements and that has a fiber-reinforced composite structure comprising a laminate having a plurality of fibers encapsulated in a matrix defining a plurality of layers, wherein a majority of the fibers in at least a mid-section of the sole between the heel and toe portions are angled at an acute angle with respect to a longitudinal axis of the sole; wherein the majority of the fibers in the mid-section of the sole are angled at an acute angle of substantially ±45°±10° to the longitudinal axis of the sole and are disposed in a first plurality of layers, and further wherein substantially the remainder of the fibers in the mid-section of the sole are either angled within ±20° of parallel to the longitudinal axis of the sole or are angled at 90°±20° to the longitudinal axis of the sole and are in one or more layers disposed between layers of the first plurality of layers. 2. The base as claimed in claim 1, wherein the mid-section of the sole covers a position anatomically beneath the location of the metatarsal bones and the plantar arch of a person wearing the ski boot. 3. The base as claimed in claim 1, wherein the one or more outsole elements comprise toe and heel outsole elements that are bonded to the toe and heel portions of the sole respectively to form a unitary construction. 4. The base as claimed in claim 3, wherein the one or more outsole elements further comprise a rigid bar outsole element that is fastened to the sole adjacent or at a forward end of the toe outsole element via at least two fasteners. 5. The base as claimed in claim 3, that is secured to an upper to form a ski boot. 6. The base as claimed in claim 4, wherein the rigid bar outsole element is fastened to the sole at the forward end of the toe outsole element, and further wherein the fasteners extend through the toe outsole element into the sole. 7. The base as claimed in claim 4, wherein the fasteners penetrate through the sole. 8. The base as claimed in claim 1, wherein between 5% and 10% of the plurality of fibers in the mid-section of the sole are oriented within 20° of parallel to the longitudinal axis of the sole. 9. The base as claimed in claim 1, wherein more than 80% of the plurality of fibers in the mid-section of the sole are angled at 45°±10° to the longitudinal axis of the sole. 10. The base as claimed in claim 1, wherein the plurality of layers comprise layers of woven fabric comprising warp and weft carbon fibre yarns encapsulated within a polymer matrix. 11. The base as claimed in claim 10, wherein the polymer matrix is an epoxy-based resin. 12. The base as claimed in claim 10, wherein the layers of woven fabric are each woven in a balanced plain weave. 13. The base as claimed in claim 10, wherein the layers of the woven fabric are oriented relative to one another and to the longitudinal axis of the sole such that in some of the layers the warp or weft yarns are angled with respect to the longitudinal axis of the sole and in at least one of the layers either the warp yarns or the weft yarns are aligned with the longitudinal axis of the sole. 14. The base as claimed in claim 10, wherein the laminate comprises at least seven layers of woven fabric. 15. The base as claimed in claim 14, wherein at least six of the layers are oriented such that their warp and weft yarns are angled at 45°±10° to the longitudinal axis of the sole and a seventh layer is oriented such that either its warp yarns or its weft yarns are aligned within ±20° of the longitudinal axis of the sole. 16. The base as claimed in claim 14, wherein the laminate comprises eight layers of woven fabric of which seven layers are oriented such that their warp and weft yarns are angled at 45°±10° to the longitudinal axis of the sole and the eighth layer is oriented such that its warp yarns or its weft yarns are aligned within ±20° of the longitudinal axis of the sole. 17. The base as claimed in claim 1, wherein the one or more outsole elements comprise rigid elastomeric elements that are bonded to the sole via an adhesive. 18. The base as claimed in claim 1, wherein the heel portion is integrally formed with an upstanding portion that is adapted to wrap up around the back and sides of the heel of a ski boot. 19.
