Abstract
Abstract A skating boot has separate ankle and toe straps, each attached to a roller or blade carrying chassis, both straps being formed as one-piece mouldings of flexible synthetic resin material. The straps are locally reinforced by thickening of the material at selected location, such as in the region of lace holes and attachment holes, and locally reduced in thickness where increased flexibility is desired such as at the edges of ankle cut-outs and tongues.
