Abstract
A first embodiment of a flexing base skate (10) includes an upper shoe portion (12) mounted on a base (14). The base includes a forefoot region (20) secured to a forward frame segment (26) carrying forward wheels (18a, 18b). A heel region (24) of the base is secured to a rearward frame segment (28) that carries rearward wheels (18c, 18d). The base defines and flexes at a reduced thickness metatarsal head portion (22), with the skater's heel and the rearward frame segment elevating freely relative to the forward frame segment. A spring (72) incorporated into the base biases the skate to the unflexed configuration. The forward frame section overlaps the rearward frame section for lateral stability. An alternate embodiment provides a rigid full length frame (112) and a flexible base (104) mounted only at the forefoot region (106) to the frame. The base (104) flexes at a metatarsal head portion (108), and is constructed to form an integral spring biasing the base against the frame. The base includes a guide (118) for lateral alignment of the heel region (110) with the frame.
