Absolutely! It's really easy (unless your skis are ANCIENT) It's not easy to do by yourself if you have no experience, but if you take them to a ski shop, the people there will happily help you Also, make sure you ask them to fill in the old screw holes from your old bindings. If not, snow/water can get in there and make your skis swell.
The bindings come with installation instructions, but if you got used bindings that didn't come with instructions... Quick question: are you putting these on new skis, or on skis that already have bindings on them? If they're old skis, remove the bindings already installed and use the old screw holes for the new bindings. If they're new skis, take them to a ski tech. You've got to drill holes in your skis and there are lots of calculations involved - how much you weigh, the skis being used and the way you ski determine where your boots should be on the ski.
Most don't but usually racing skis do
Yes, but if you can afford either new skis or new bindings, get the new bindings because they'll keep you safer on the slopes.
That depends on what you mean by regular bindings. You can use cross-country bindings but not alpine bindings.
Because if skis were short and round, they would be called "bicycles".
Alpine Touring, also known as Randonnée, is a type of backcountry skiing. Randonnée ski bindings are a cross between standard downhill bindings (toes and heels locked in) and telemark bindings (only toes locked in). With randonnée bindings, the skier can clip down the heel piece when skiing downhill (like downhill bindings) and release it when skating or climbing (like telemark bindings). Special ski boots are used with both telemark and randonnée; though, randonnée boots have rigid soles like standard downhill boots. Also, randonnée bindings can release during falls, but telemark bindings cannot. And a skier need not learn to turn differently on AT skis, as with telemark skis, since the heel can be clipped down. As for the skis themselves, AT skis are typically much wider and heavier than a basic ski-area ski, as they are used more often in deep powder and ungroomed conditions; though, randonnée bindings can be mounted to most skis. All Mountain skis are a mid-width type of ski, such that the skier can handle well in both groomed and ungroomed/powder conditions--the latter not as well as with AT skis.
Better to have both with good condition
Mine weigh 9kg inc bindings
no it is really bad for your skis you will probably get hurt
There are different types of binding for different types of skiing. Alpine ski binding fasten the boot to the ski at the heel and tow and allows the boot to release during falls. There are three Nordic binding systems for cross country skiing. Cross country skies usually slide a bar in the shoe into a catch.
About the same as they do right now, except in 1860 skis and poles were wood and the bindings were leather straps. The biggest change is in the bindings, which are made to release when a certain amount of force is exerted against them to keep you safe.
