  • Patent number: 6311415
    Abstract: A bowling shoe with a replaceable tip comprises a shoe upper, a shoe sole mounted to the shoe upper, and a plurality of replaceable shoe tips. The shoe sole has a selectable traction area from a toe end and across the width of the shoe sole. Each tip has a margin substantially equal to a margin of the traction area. Each tip covers and conforms to part of the adjacent shoe upper. The surface of each tip has a different coefficient of friction. A selected tip secures to the traction area and part of the adjacent shoe upper. The tips are interchangeable, to provide traction according to support surface conditions and an individual wearer's preference.

  • Patent number: 6243973
    Abstract: A wedge-soled bowling shoe has selectable percentages of regions of different coefficients of friction of traction characteristics and different coefficients of friction of slide characteristics on a shoe sole surface. The shoe gives the bowler precise control over relative amounts of slide and/or traction action of each shoe. The bowler can readily change the relative amounts of slide and/or traction action of each shoe by changing a replaceable sole member of the desired percentages of regions of high or low traction and high or low slide to accommodate differing conditions and differing styles of bowling. Using one of a plurality of pairs of replaceable sole members, a first member of each pair is constructed of two materials, each of a different coefficient of friction to provide slide characteristics and a second member of each pair is constructed of two materials, each of a different coefficient of friction to provide traction characteristics.
