Abstract

In-line roller skate including a soft, pliable, and comfortable shoe body having structural foot support components positioned in selected strategic areas such as the ball, heel, and ankle. The shoe body may be made of a material that allows air circulation for coolness. In one embodiment, the structural components are made of semi-rigid plastic that may be heat moldable to conform to the user'"'"'s foot. The shoe sole may also include heat moldable materials so that it can be anatomically formed to the foot. The shoe is mounted on a frame that supports a plurality of in-line roller wheels and includes structure for easily removing and replacing the wheels. The shoe-frame connection may be laterally and longitudinally adjustable. A speed control or brake, which applies a frictional force downwardly onto some or all of the in-line roller wheels, is mounted on the frame. Canting adjustment is provided to allow the ankle support to be canted laterally or longitudinally.

Claims

1. An in-line roller skate for receiving a skater'"'"'s foot, the skate comprising:

a frame having a plurality of longitudinally aligned wheels rotatably secured thereto;

a base securely attached to the frame, the base including a heel portion and a toe portion;

a flexible and breathable shoe portion adapted to receive the skater'"'"'s foot, wherein the shoe portion is attached to an upper portion of the base; and

a semi-rigid upper portion that is secured to the base, the semi-rigid upper portion including a heel counter secured to the base and an ankle support cuff pivotally coupled to the heel counter, the ankle support cuff further comprising a support strap, the semi-rigid upper portion providing lateral support for the shoe portion while leaving a part of the shoe portion exposed during use.

2. The in-line roller skate of claim 1, wherein the shoe portion is permanently affixed to the base.

3. The in-line roller skate of claim 1, wherein the ankle support cuff is slidably coupled to the shoe portion.

4. The in-line roller skate of claim 1, wherein the ankle support cuff is non-permanently coupled to the shoe portion.

5. The in-line roller skate of claim 1 wherein the base is contoured.

6. The in-line roller skate of claim 1 wherein the frame is made from a composite material.

7. The in-line roller skate of claim 1 wherein at least a portion of the base is made of a heat moldable plastic such that the base can be anatomically fitted to the skater'"'"'s foot.

8. The in-line roller skate of claim 1 wherein the shoe portion comprises a forward toe end, and further wherein the toe portion of the base extends over at least a part of the forward toe end of the shoe portion, thereby providing protection to the shoe portion.

9. The in-line roller skate of claim 8 wherein the toe portion of the base is laminated to the forward toe end of the shoe portion.

10. The in-line roller skate of claim 1 wherein the ankle support cuff is hingedly attached to the heel counter.

11. The in-line roller skate of claim 1 further comprising a canting system for longitudinal tilt adjustment of the ankle support cuff.

12. The in-line roller skate of claim 11 further comprising a canting system for lateral tilt adjustment of the ankle support cuff.
