11. An ice skate boot as defined in claim 10 , wherein said medial and lateral skirt portions are thermoformed such that they comprise a front pedestal, a rear pedestal and a bridge portion interconnecting said front and rear pedestals, said medial and lateral apertures being located between said front and rear pedestals and above said bridge portion.
12. An ice skate boot as defined in claim 11 , wherein said medial and lateral bottom and toe portions are affixed together along a longitudinal line.
13. An ice skate boot as defined in claim 12 , wherein said medial and lateral skirt portions are integrally formed together at a rear portion of said rear pedestal.
14. An ice skate boot as defined in claim 12 , wherein said medial and lateral skirt portions are integrally formed together at a front portion of said front pedestal.
15. An ice skate boot as defined in claim 6 , wherein said medial and lateral toe portions are integrally formed together for forming an integrated toe cap.
16. An ice skate boot as defined in claim 6 , comprising a tongue extending upwardly and rearwardly from said medial and lateral toe portions.
17. An ice skate boot as defined in claim 6 , comprising a tongue that is integrally formed with one of said medial and lateral side portions.
18. An ice skate boot as defined in claim 15 , comprising a tongue extending upwardly and rearwardly from said toe cap.
19. An ice skate boot as defined in claim 18 , wherein said tongue is integrally formed with one of said medial and lateral side portions.
20. An ice skate boot as defined in claim 1 , wherein said composite sheet comprises an outer layer and an inner layer, said outer layer being more rigid than said inner layer.
21. An ice skate boot as defined in claim 20 , wherein said composite sheet comprises a layer of thermoformable foam between said outer and inner layers.
22. An ice skate boot as defined in claim 6 , wherein said composite sheet comprises layers of different grades of thermoformable foam.
23. An ice skate boot as defined in claim 1 , wherein said heel portion is substantially cup shaped for following the contour of the heel of the foot.
24. An ice skate boot as defined in claim 23 , wherein said ankle portion comprises a cup-shaped lateral depression for receiving the lateral malleolus and a cup-shaped medial depression for receiving the medial malleolus.
25. An ice skate boot as defined in claim 24 , wherein said lateral cup-shaped depression is below said medial cup-shaped depression.
26. An ice skate boot as defined in claim 1 , comprising an inner lining affixed to an inner surface of said outer shell, said inner lining comprising a surface intended for contact with the heel, ankle and medial and lateral sides of the foot.
27. An ice skate boot as defined in claim 1 , comprising a footbed having an upper surface facing the plantar surface of the foot and a wall projecting upwardly from said upper surface, said wall partially cupping the heel and extending up to a medial line of the foot.
28. A method of manufacturing an ice skate boot, said method comprising:
(a) providing a composite sheet comprising a layer of thermoformable material;
(b)thermoforming said composite sheet to form an outer shell for enclosing a human foot, the foot having a heel, an ankle with a medial malleolus and a lateral malleolus, a plantar surface, medial and lateral sides and toes, said outer shell comprising:
(i) a heel portion for receiving the heel of the foot;
