Ski lashings are devices that secure the boot to the ski. The lashings must always be compatible with the type of ski boot. Different types include alpine, snowboard, backcountry, telemark and Kandahar.
Kandahar ski moorings are cable moorings. They secure the foot in an advanced position in the mooring using a cable. Cable lashings are not interchangeable with three-prong lashing systems.
Some types of lashings only secure the toe area of the boot to the ski.
New Nordic Norm (NNN) telemark ski tethers are available in cable and three-prong styles. The three-prong style has three prongs off the base with a metal clamp to secure the cover. The pegs must be placed firmly in the holes in the toe of the boot. Cable lashings can be more expensive than three pegs, but they are less likely to damage ski boots than peg types.
The boots fit into the ski lashings.
New Nordic Norm Backcountry (NNN-BC) ski links are not interchangeable with NNN links. NNN and NNN-BC lashings are compatible with different ski boots. Some skiers find the NNN-BC type more comfortable than the NNN systems due to the placement of the fastening hardware under the toe area rather than in front of the ski boot toe.
NNN-BC ski tethers are used with some telemark boots to provide a lighter ski system. Ski boot material can make a difference in lacing. Some skiers recommend plastic boots to control turns, while others say some plastic ski boots are heavy and less comfortable than leather or NNN-BC boots. Telemarking on slopes often requires a stiffer ski boot, while skiing in remote areas may require a lighter ski boot.
Alpine touring ski lashings are designed to fit the heel in a unique way: when climbing, the heel is free. This type of lacing lifts the heel to keep it free while the toe area remains level during the climb. When skiing, both the heel and the toe are attached as in alpine ski lashings. The Alpine Touring Boots, which feature a plastic shell, rigid sole and removable inner lining, are only used with Alpine Touring buckles. Most of these tethers are pressure sensitive and designed to release when the weight of a falling skier makes contact with them.
Snowboard bindings are generally available in small, medium and large sizes. Different types have different shaped heel pads and base plates. Most snowboarders buy their snowboard first and then find the proper lashings.
