  • Patent number: 6324773
    Abstract: An internal lacing system wherein a plurality of lace guides having rotatable rollers are strategically positioned throughout a shoe to facilitate the securing of the foot within the shoe. First and second elongated laces are internally channeled through the respective lace guides and then exit the internal of the shoe at the inner side of the shoe. One end of the first elongated lace is secured within the shoe proximal to the toe area, and the other end of the first elongated lace exits the internal of the shoe at lower inner side portion of the shoe proximal to the sole of the shoe. One end of the second elongated lace is secured within the shoe proximal to the exit location of the other end such that the second elongated lace wraps around the heel of the shoe and thus around the user's ankle. To tighten the shoe, a user simply pulls on the exposed second ends of the first and second laces thereby allowing the laces to roll along each respective roller positioned within each lace guide.

  • Patent number: 6286233
    Abstract: An internal lacing system for footwear wherein a plurality of lace guides having rotatable rollers are secured and strategically positioned throughout a shoe to facilitate the securing of the foot within the shoe. More specifically, an elongated lace having a first end and a second end is internally channeled through each of the lace guides and over the respective rollers, wherein the second end of the elongated lace exits the internal of the shoe at the upper portion of the shoe proximal to the shoe opening. The first end of the elongated lace is secured within the shoe proximal to the toe area of the shoe. To tighten the shoe, a user simply pulls on the exposed second end of the lace thereby allowing the lace to roll along each respective roller positioned within each lace guide. Additionally, because the first end of the lace is fixed, the pulling on the second end of the lace will result in a reciprocating force about each lace guide thus securely tightening the shoe around the user's foot.
