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 the foot of a skater, 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 rigid sole having a heel portion and a toe portion adapted to support the bottom of the skater'"'"'s foot, the base further including an at least semi-rigid heel counter secured to the heel portion and an at least semi-rigid toe cap secured to the toe portion;

an upper shoe portion formed from a substantially flexible material, at least a part of the upper shoe portion being breathable, the upper shoe portion adapted to substantially cover the instep and ankle of the skater'"'"'s foot and being attached to the base such that at least a part of the upper shoe portion is in contact with the sole, the upper shoe portion further including a releasable fastener adapted for securing the upper shoe portion around the foot of the skater, iucluding the instep of the skater'"'"'s foot; and

an at least semi-rigid ankle support cuff having an adjustable support strap, the ankle support cuff being pivotally coupled to the heel counter to provide lateral support for the upper shoe portion and leaving a substantial part of the upper shoe portion exposed during use, including a majority of the part of the upper shoe portion that is over the instep of the skater'"'"'s foot.

2. The in-line roller skate of claim 1, wherein the upper shoe portion is laminated to the toe cap.

3. The in-line roller skate of claim 2, wherein the ankle support cuff is slidably coupled to the upper shoe portion.

4. The in-line roller skate of claim 3, wherein the heel counter is rigid.

5. The in-line roller skate of claim 4, wherein the toe cap is formed from plastic.

6. The in-line roller skate of claim 5, wherein the ankle support cuff is rigid.

7. The in-line roller skate of claim 1, wherein the heel counter is an integral part of the base.

8. The in-line roller skate of claim 1, wherein the upper shoe portion further comprises an external lace cover.

9. The in-line roller skate of claim 1, wherein the rigid sole is contoured to include an arch support.

10. The in-line roller skate of claim 1, wherein the base is adjustably fastened to the frame.
