Abstract: An expandable article of footwear having a sole with an upper formed over at least a portion of the sole. At least a part of the upper has formed therein an array of elongated slits. The slits are colinearly arranged into substantially parallel columns with the slits spaced part in the columnar direction. The slits of adjacent columns are in staggered relationship with each other. In this manner, when the article of footwear is worn, the openings defined by the slits expand into a generally oval shape.

Abstract: An article of footwear having a shoe portion including an upper with a mouth, and a tubular portion adapted to be selectively coupled to the shoe portion. A fastener interconnects one end of the tubular portion to the mouth of the upper. A reversible cuff on the tubular portion is available to conceal the connected fastener and a reversible collar on the shoe portion is available to conceal the unconnected fastener and to prevent any abrasive contact with the leg of the wearer. When the shoe portion is used alone there is provided an ankle boot, and when used in combination with the tubular portion there is provided a calf high boot.
