Description

A WINTER SPORT/SNOW BOOT

BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates generally to boots used in conjunction with recreational activities and daily purposes and more particularly to boots used after snow skiing or snowboarding and for other non-recreational purposes.

2. State of the Art

Skiing and snowboarding are sports that require a rigid ski boot for providing the proper support for the various terrains that a user may encounter when descending a run. These boots often do not have a typical walking sole and are adapted to clip onto skis. In addition, ski boots are designed to support a user's ankle and lower leg to help provide stability and avoid injury. The very specific purpose of a ski boot makes them difficult and uncomfortable to walk in. This type of specialized foot equipment is not specific to skiing and snowboarding alone, but similar footwear may be used for other snow recreational activities.

Skiers often times wish to change into other types of footwear than that used for their winter sport. These alternate types of footwear are generally full size and are not easily transported. They require the use of a locker or other storage unit and often require some walking to reach the storage. While other types of footwear may be smaller with less bulk than the ski boot, they lack the warmth, water-resistance and traction that conventional snow boots provide while walking in snow.

In addition snow sport boots often retain snow and ice in the narrow boot crevasses. Inadvertently carrying the ice and snow can cause a variety of difficulties such as forming slippery areas at the resort or residence. The size and weight of the boots also limits agility and can create situations where tripping may occur. In extreme situations those wearing boots may be tempted to leave their boots on while they drive to their lodge, residence or nearby ski area. Doing so reduces reaction time and can cause interference when moving from one pedal to another.

When renting equipment it is generally required that the renter turn in their footwear to receive their boots. Mistakes in this procedure are common. Also, the renter has to go without alternate footwear until the boots are returned, which is generally at the end of the outing or trip.

In addition to skiing or alternate snow sports and recreation, other winter activities take place, which require interaction with snow, ice, slush or water are common. Tasks around a home such as shoveling snow, feeding or walking animals, getting the mail or other activities such as traveling to work or school and various other types of everyday activities that take place during the winter season, all subject the participant to the elements. Conventional boots are big and bulky and often have other types of limitations and problems. For example, a child wearing a boot to school will often retain snow and ice in the narrow boot crevasses. Inadvertently carrying the ice and snow can cause a variety of difficulties such as forming slippery areas in the school hall and/or classroom. Additionally, storing the boots to put on other footwear while at school is difficult due to the size of the boot. Other problems may also exist due to the size of the boot and the common inefficient insulation and in flexibility of the boot.

Accordingly what is needed is a winter boot that is portable during skiing or other snow sports and recreational activities that may be worn after the sports or for other daily purposes and provides proper warmth, protection, traction, and water- resistance in snow. DISCLOSURE OF THE INVENTION

The present invention relates to a boot that is portable during skiing and other snow sports and may be conveniently accessed and used during breaks and down-time, or used for other daily purposes. While particular embodiments are most useful for after snow activities, other embodiments of the invention are useful after all forms of snow recreational activities and for daily purposes. In particular embodiments, the snow boot comprises a flexible, water-proof, breathable outer material, a liner, a first fastener coupled toward the toe of the boot, a second fastener coupled toward an upper portion of the boot and an attachment device which may be an elastic strap.

In particular embodiments, the winter sport boot folds into a closed position with the first fastener and the second fastener coupled together to retain the boot in a closed position for portability. The attachment device may be, but is not limited to a clip, a D- ring, an O-ring, a strap and any device wherein the attachment device may be used to secure the boots to a compatible attachment device during skiing.
