,~ A portion of runner 12 is illustrated in Figure 6 ,~ and reference will now be made thereto. Runner 12 includes a ;~
metallic ice contacting blade 16 and a blade holder generally :~
designated by reference numeral 18. Blade holder 18 is ~; formed of a suitable plastic material and it is adapted to ~: retain the blade 16 in the desired position,and act as the connecting portion between blade 16 and boot 14. As may be ,~.
~.~: seen from Figures 3 and 4, blade ho]der 18, in the illustrated .', ~ embodiment, is formed with three sections extending vertically '::~
between the boot and blade 16 with one situated at the front of the skate, another at the rear and one intermediate the front and rear of the skate. Each of the sections of blade .

slade 16 as shown in Figure 6, has along an upper edcJe thereof and located at a]ternate ends of the .
1~1L1dC ul)wardly extel~dillg portions 20, each of~which has an perture 22 extendinq -therethrough. Apertures 22 serve as ,~j ~ anchoring points for the plastic as discussed hereinbelow.
,~ r~ocated at the central portion of b]ade 16 is a further ;i upwardly extending portion 24 which has a generally T-shapedconiguration: a pair of arms 26 extend in opposite directions I:oward the front and rear of -the skate. Thus, during the manufacture of the skate wherein blade holder 18 is formed by injection molding, the molten plastic material ~lowa through apertures 22 and about arms 26. When the plastic material starts to solidify, there is a shrinkage o~ the plastic in the lengthwise direction as indicated by arrows 28.
This shrinkage is controlled and guided by th~ design of the blade so that the blade remains embedded and solidly supported in the plastic with minimized internal stress. As will be noted in FigureS 1, 2 and 6, an aperture or slit remains in the plastic above portlon 24 to again minimize stress in the ;~
solidifecl plastic. ~

As previously mentioned, in conventional skates, the blade holder and the boot portion are formed separately with the blade holder being secured to the boot by suitable means (normally mechanical fasteners). A feature of the present invention is that the boot is formed in a single . ~
oper~tioll with the b~ade ho]der being formed integral]y with at least a portion of the boot.
~i As shown in Figure 5, a conventional mold `I arrangement is utilized. The mold comprises two mold halVes '~ 28 movable as shown by arrows 30. A last 32 is provided for the boot portion and mold haves 28 include portions 34 to form the runner of the skate.
,~ In manufacture, and referring to Figures 3 to 9, last 32 is provided with an outer liner 36 of a suitable material (such as a reinforced nylon) formed thereabout.
An inner liner, (not shown) of a suitable material may also be provided. The mold is then closed and a molten plastic material injected to a runner system generally designated by reference numeral 38. As may be seen in Figure 3, the molten plastic will flow to form the blade holder 18, a foot A I I
bed 40, a toe portion 42, and a hee] portion 44. As will be ; seen from Figures 3 and 8, there is provided a mold section 46 pivotable about pivot point 48 which has a runner system 38' - ~:
~¦ therein, the runner system 38' being adapted to allow the plastic to ~low from toe section 42 to form eyelets 48 for event~ cil~l o~ t-~c ~oot.
As shown in Figure 9, the last includes a section S0 adapted to stabilize and hold the last in the desired positlon while being injection molded.

In one embodiment of the present invention, the section generally designated by reference numeral 52 in Figure 3 may be replaced by a further section as shown in igures 10 and 11. As shown therein, a runner 54 is provided i.~.i ~i to commu~icate with heel section 44 thereby permitting an uppar se(tioll 56 to be formed of the p]astic materia], wllicll ~ )or SOC~iOIl 56 is prc)~illl.lte the allkle of the wearer to provide additional support. A removable insert 58 is provided additional support. A removable insert 5B is provided for the mold to allow for the upper section 56 to ~
be formed as illustrated. Mold insert 58 is suitably secured i; to the mdin body of the mold by mechanical fasteners 60.
Following the molding of the shell about the boot ~;, with the integral blade holder, a conventional tongue 62 may be provided.
During the molding operation, the outer liner 36 may, if required, be treated to ensure proper adherence of the molten plastic to the liner. Suitable treatment for the liner is known to those skilled in the art. As will be seen from the above, the use of an injection molding system to form an integra] blade holder and boot she]] greatly simplifies the manufacturil)g process compared to the operation~ wherein i~ was required to form a separate runner and subsequently attach the same to the boot portion.
