20140042718 | BIOMECHANICAL ARTICULATING SKATE - An ice skate in the foam of a boot that surrounds a foot, ankle and preferably the lower leg of a user. The boot has a heel portion and toe portion and a metatarsal hinge facilitating rotational movement of the heel portion with respect to the toe portion about this hinge. The anterior and posterior blades have substantially linear edges for selectively contacting an ice surface, the blades being biased by use of a spring extending from the heel of the skate to the holder of the anterior blade. | 02-13-2014 |
