Abstract
Abstract An insert for use in ice skates and the like which includes a blank having a top layer with an upper surface provided with a contour substantially complemental to the plantar surface of a person's foot, the top layer formed from a suitable material to resist abrasion, and absorb perspiration. The top layer is bonded to an intermediate layer formed of resilient material, a bottom portion of the intermediate surface affixed to a lower surface having a bottom layer provided with an alignment device for registry with the center line of a skate whereby deformation of the blank occurs along its longitudinal axis thereof, directly above the skate blade, the deformation of the blank causing a cradling and supporting effect upon the foot disposed within the skate so as to provide not only better centering over the skate blade, but also an improved load transmission from the foot through the leg resulting in overall better balance and skate edge control.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
81 words
An insert adapted for insertion and wearing use within a boot or the like, comprising in combination; a blank having a top layer with its upper surface generally contoured to conform to the plantar surface of a person's foot, a lower layer having a bottom face provided with a recess substantially extending rearwardly from the metatarsal to the calcaneal area of the foot, the metatarsal area itself of uniform thickness along an entire metatarsal head area and transverse to said recess.
Claim 2
Dependent Claim
81 words
An insert adapted for insertion and wearing use within a boot or the like, comprising in combination; a blank having a top layer with its upper surface generally contoured to conform to the plantar surface of a person's foot, a lower layer having a bottom face provided with a recess substantially extending rearwardly from the metatarsal to the calcaneal area of the foot, the metatarsal area itself of uniform thickness along an entire metatarsal head area and transverse to said recess.
Claim 3
Dependent Claim
25 words
The device of claim 1 in which said recess is provided with feathered leading and trailing edges proximate to the metatarsal and calcaneal areas respectively.
Claim 4
Dependent Claim
17 words
The device of claim 2 in which marginal portions are provided on lateral sides of said recess.
Claim 5
Dependent Claim
20 words
The device of claim 3 in which said marginal portions have a curved contour, extending upwardly to said upper surface.
Claim 6
Dependent Claim
47 words
The device of claim 4 in which a peripheral lip extends around the heel calcaneal area of the foot, tapering toward the metatarsal area of the insert whereby deformation of said recess provides corresponding deformation of said lip to grasp more tightly the heel of the foot.
Claim 7
Dependent Claim
25 words
The device of claim 5 wherein an intermediate layer is provided between said top and lower layers said intermediate layer formed of a resilient material.
Claim 8
Dependent Claim
22 words
The device of claim 6 in which said lower layer is formed from a foam material having a memory and damping properties.
Claim 9
Dependent Claim
19 words
The device of claim 7 in which said top layer is formed from an abrasion resistant and absorbent material.
Claim 10
Dependent Claim
91 words
An insert adapted for insertion within an ice skate or the like, comprising in combination: a blank having a top layer with its upper surface generally contoured to conform to the plantar surface of a person's foot, a lower layer having a bottom face provided with a recess substantially extending from the metatarsal to the calcaneal area of the foot, said recess centrally disposed over a blade of the ice skate in which said recess is provided with feathered leading and trailing edges proximate to the metatarsal and calcaneal areas respectively.
Claim 11
Dependent Claim
91 words
An insert adapted for insertion within an ice skate or the like, comprising in combination: a blank having a top layer with its upper surface generally contoured to conform to the plantar surface of a person's foot, a lower layer having a bottom face provided with a recess substantially extending from the metatarsal to the calcaneal area of the foot, said recess centrally disposed over a blade of the ice skate in which said recess is provided with feathered leading and trailing edges proximate to the metatarsal and calcaneal areas respectively.
Claim 12
Dependent Claim
17 words
The device of claim 9 in which marginal portions are provided on lateral sides of said recess.
Claim 13
Dependent Claim
20 words
The device of claim 9 in which said marginal portions have a curved contour, extending upwardly to said upper surface.
Claim 14
Dependent Claim
47 words
The device of claim 9 in which a peripheral lip extends around the heel calcaneal area of the foot, tapering toward the metatarsal area of the insert whereby deformation of said recess provides corresponding deformation of said lip to grasp more tightly the heel of the foot.
Claim 15
Dependent Claim
25 words
The device of claim 9 wherein an intermediate layer is provided between said top and lower layers said intermediate layer formed of a resilient material.
Claim 16
Dependent Claim
22 words
The device of claim 9 in which said lower layer is formed from a foam material having a memory and damping properties.
Claim 17
Dependent Claim
19 words
The device of claim 9 in which said top layer is formed from an abrasion resistant and absorbent material.
Claim 18
Dependent Claim
29 words
The device of claim 9 in which said recess is configured to define a central longitudinal line which is to be substantially co-planar with the blade of the skate.
Claim 19
Dependent Claim
22 words
The device claim 9 in which said recess is configured to be offset laterally with respect to the blade of the skate.
