Bindings now come with varying compatibility for the different types of boot soles. The majority of people will just want the standard alpine downhill binding however for those who plan on touring you will want to make sure that the touring boots you use are compatible with the bindings. Below is a description on all types of sole compatibilities for you to make sure your boots and bindings work together.
If you are just using standard alpine downhill boots like the majority of people, then you will want to use compatible Alpine Downhill bindings. Standard Alpine Downhill soles are referred to as ISO 5355’s and are compatible with the standard regular binding that you see on the mountain. If you are not wanting touring bindings or boots then these are the go to. If you are skiing regular downhill runs then these are the binding compatibility that you want
Tour bindings are specifically designed for walking uphill with the use of ski skins and are made to help you with backcountry skiing. These bindings are compatible with boots that use rockered or touring soled boots which use the terminology of ISO 9523. These do not work with standard alpine boots (ISO 5355) so make sure not to use these bindings if you are using if you’re using standard alpine downhill boots.
Tech bindings are relatively new tour bindings that feature a series of pins that interface with the ‘tech inserts’ in the toes and heels of compatible boots. The advantages of this is they are extremely lightweight, but they do require a compatible boot.
WTR-designated bindings are compatible and specifically designed for WTR ski boots. However, some traditional alpine boots (ISO 5355) are also compatible with these bindings. There are some newer models of WTR bindings that are compatible with all three standards of boots – WTR, ISO 5355 and ISO 9523.
These bindings are compatible with all three different ski boots – WTR, ISO 5355 and ISO 9523.
This section is to help those looking for telemark bindings to narrow down their search. Telemark bindings are bindings that only clip in the toe of your boot and let the heel flex and lift during turns. This allows for a new experience of skiing. If you are looking for regular ski equipment, ignore this section.
This section is to help those looking for cross-country bindings to narrow down their search. Cross-country bindings are bindings that only clip in the toe of your boot and are specifically designed for trail skiing or long distance/uphill skiing. If you are looking for regular ski equipment, ignore this section.
All ski bindings are required to have safety brakes. Safety brakes come in many different widths and are often replaceable. When purchasing safety brakes for your skis, make sure that the safety brake width (the distance between the two brake arms) is at least as wide as the waist of the ski you intend to put it on. For example, if your skis are 90mm wide at the waist, you will need bindings with a brake width of at least 90mm and no wider than 105mm. Please note, most ski bindings do not come with safety brakes and they will need to be purchased separately.
