In certain instances each ice-skate blade post is a multi-degree of freedom adjustable cup that adjusts the position of an ice-skating blade relative to the ice-skate boot sole. Each ice-skate adapter generally comprises a skate sole end that attaches to an ice-skate boot sole and a skate end that attaches to a respective ice-skate blade post. A cup body is defined between the skate sole end and the skate end. The skate sole end comprises a surface that conforms to the shape of the ice-skating boot sole. For added stiffness and stability, the skate sole end further comprises a plurality of appendages that extend outwardly from the cup body. ## Claims ### Claim 1 An ice skate adapter comprising: a cup body defined between a skate sole end and a skate end, said skate sole end extending toward said skate end in a vertical direction; a sole interface surface defined at said skate sole end and including at least a portion of said skate sole end, said sole interface surface conforming to a skate sole; at least two appendages extending outwardly from said cup body in a horizontal direction, said at least two appendages form part of said sole interface surface, said at least two appendages resistant to vertical bending forces in said vertical direction; each appendage comprising an adapter-to-sole attachment member located towards an appendage distal end, said skate sole end configured to attach to said skate boot sole via said adapter-to-sole attachment members and said skate end configured to attach to a skate blade; and said sole interface surface is not parallel with a cup interface surface, said cup interface surface is at said skate sole end. ### Claim 2 (depends on 1) The ice skate adapter of claim 1 wherein said sole interface surface is concave. ### Claim 3 (depends on 1) The ice skate adapter of claim 1 wherein said sole interface surface is non-planar. ### Claim 4 (depends on 1) The ice skate adapter of claim 1 wherein each of said adapter-to-sole attachment members comprises a bolt hole. ### Claim 5 (depends on 1) The ice skate adapter of claim 1 wherein said ice skate adapter is unitary. ### Claim 6 (depends on 1) The ice skate adapter of claim 1 wherein said appendages each comprising a web that increases the secondary moment of inertia of said appendage corresponding to said web. ### Claim 7 (depends on 1) The ice-skate adapter of claim 1 wherein said skate end is configured to attach to said skate blade via an adjustable ice-skate blade post. ### Claim 8 (depends on 1) The ice-skate adapter of claim 1 comprising six appendages when it is a rear ice-skate adapter and wherein said ice-skate adapter comprises comprising eight appendages when it is a front ice-skate adapter. ### Claim 9 (depends on 1) The ice-skate adapter of claim 1 wherein said cup body has a cup body diameter of between 1 inch and 2.5 inches. ### Claim 10 An adjustable ice-skate blade-to-boot connector comprising: a cup body defined between sole interface surface and a cup surface, the sole interface surface conforming to a portion of a skate boot sole; a plurality of appendages extending outwardly from said cup body, said plurality of appendages are part of said cup surface; a bolt receiving aperture located at a distal end of each of said appendages; and a bolt receiving aperture extending through said cup surface, said bolt receiving aperture configured to connect said connector with an ice-skate blade post, said sole interface surface is concave. ### Claim 11 (depends on 10) The adjustable ice-skate blade-to-boot connector of claim 10 wherein at least two of said bolt receiving apertures are defined by a bolt aperture ring, each of said bolt aperture rings is located at said distal end of a corresponding appendage of said appendages, each of said bolt aperture rings is wider than at least a portion of said corresponding appendage. ### Claim 12 (depends on 10) The adjustable ice-skate blade-to-boot connector of claim 10 wherein each of said appendages comprises a thickness of between 0.2 inches and 0.5 inches thick. ### Claim 13 (depends on 12) The adjustable ice-skate blade-to-boot connector of claim 12 further comprising a cup body-to-appendage web that is triangular-shaped and extends from said cup body towards said distal end but does not interfere with said bolt receiving aperture. ### Claim 14 (depends on 10) The adjustable ice-skate blade-to-boot connector of claim 10 wherein at least two of said appendages comprises a width between 0.2 inches and 0.75 inches wide. ### Claim 15 (depends on 10) The adjustable ice-skate blade-to-boot connector of claim 10 wherein said adjustable ice-skate blade-to-boot connector is composed from a unitary piece of material. ### Claim 16 An ice skate joiner comprising: a cup body defined between a first end and a second end; a plurality of appendages extending outwardly from said cup body, said plurality of appendages collectively define a boot sole surface that conforms to a portion of a skate boot sole, said boot sole surface is at said first end; a bolt receiving aperture located at a distal end of each of said appendages, at least two of said appendages each comprising a ring surrounding said bolt receiving aperture, said ring larger than an appendage width of said corresponding appendage; and said second end defining a ice-skate blade post interface surface that is matingly engaged with an ice-skate blade post via a locking bolt. ### Claim 17 (depends on 16) The ice-skate joiner of claim 16 comprising at least one appendage-to-appendage web that span between two adjacent appendages. ### Claim 18 (depends on 17) The ice-skate joiner of claim 17 wherein at least one of said appendage-to-appendage webs further defines said boot sole surface.
