LW1 is a para-alpine standing skiing classification for people with severe lower extreme disabilities in both extremities. It includes both skiers with amputations and cerebral palsy. International classification is done through IPC Alpine Skiing, and national classification through local national sport federations. LW1 classified skiers use outriggers, and two skis or one ski with a prosthesis. Other equipment is used during training such as ski-tips, ski-bras, and short skis.

As this classification includes skiers with cerebral palsy and amputations, there are different skiing techniques used specific to these disability types. For skiers with amputations falling is an important skill to learn, while addressing balance is an important thing for skiers with cerebral palsy to master.

A factoring system is used to allow LW1 competitors to fairly compete against skiers in other standing classifications. At events such as the 1990 Disabled Alpine World Championships, this class had its own medal events. In later events such as the 2002 Winter Paralympics, it was grouped with other classes for a single medal event. Skiers in this class include New Zealanders Adam Hall and Kevin O'Sullivan.

LW1 is a standing classification used in para-alpine skiing but not para-Nordic skiing. LW stands for Locomotor Winter, and the classification is for people with severe lower extreme disabilities in both extremities. They may have cerebral palsy and be classified as CP5 or CP6, or have spina bifida. The International Paralympic Committee explicitly defined this class as "Competitors with severe disabilities in both lower limbs ... The typical disability profile of the class is double above-knee amputation." In 2002, Australian Paralympic Committee defined this classification as a standing skiing classification with "Two skis, two poles, disability in both legs above the knees."

For international competitions, classification is done through IPC Alpine Skiing. A national federation such as Alpine Canada handles classification for domestic competitions. When being assessed into this classification, a number of things are considered including reviewing the skiers medical history and medical information on the skier's disability, having a physical and an in person assessment of the skier training or competing.

LW1 classified skiers use outriggers, and two skis or one ski with a prosthesis. International Ski Federation rules for ski boots and binding heights are modified for this class and are not the same rules used for able-bodied skiers. Skiers in this class are allowed to use ski-tips in competition, using a setup sometimes called a Four Track. In training, they may use additional equipment. For example, skiers with cerebral palsy may use cants, wedges, ski-bras, outriggers or short skis depending on the nature of their disability. Skiers with an amputation may use a prosthesis. As skiers in this classification improve, they require less use of this equipment. Ski bras are devices clamped to the tips of skis, which result in the skis being attached to each other. Outriggers are forearm crutches with a miniature ski on a rocker at the base. Cants are wedges that sit under the binding that are intended to more evenly distribute weight, and are customised for the specific needs of the skier. In the Biathlon, athletes with amputations can use a rifle support while shooting.

As this classification includes skiers with cerebral palsy and amputations, there are different skiing techniques used specific to these disability types. While skiing, competitors have a wider turning radius as a result of their disability.

For skiers in this class with above the knee amputations, how to fall properly is an important skill. They are taught to try to prevent the stump of their leg from hitting the snow as it can cause more damage to that leg than the one that is not partially missing. When working on side stepping, the skier is supported to keep the stump of their leg on the uphill side. Elite skiers are taught to avoid using outriggers as crutches. They are taught to turn using their leg instead of their ski poles. In getting on ski lifts, skiers in this classification with amputations are taught to lift their outriggers off the ground and point them forward.
