This is it! You've finally chosen the perfect pair of skis for you ! Now, before you set off to tackle your favourite slopes in Val Thorens, there's one last important step: adjusting your bindings correctly.
To ski in complete safety and allow the binding to play its role both in supporting your feet and protecting your knees in the event of a fall, there are a number of parameters to take into account:
- Ski level
1) Adjust the binding to the ski boot
First of all, you need to find out the length of your shoe: this is usually engraved on the heel or side of the shoe and expressed in millimetres.
This size will allow you to adjust the front of your binding: on the new models, the system is simplified and you only have to pull on the tab to unlock the adjustment system. You need to slide the front of your binding until you reach the number range in which your shoe size falls, keeping the tongue raised:
Example: If my shoe size is 296 mm, I move my binding until I reach the 292 mm/ 300 mm range.
To lock the fastener, simply clip the tab again.
The same adjustments need to be made on the back of the binding. Once again, use the tab to unlock the device, and slide the binding to the gap corresponding to your shoe size.
You may need to adjust your settings slightly in relation to the measurements: enter the front of the shoe into the binding, then the back. When you press down on the shoe, it should click into place easily, and the two ends of the shoe should be well seated in the binding.
Now that you've adjusted your binding to your shoe, it's time to move on to the weight:
2) Set the trigger value
This setting is very important, as it will determine the binding release threshold in the event of a fall. It must not be too high so that your skis come off in the event of a fall (and thus protect your knee from the all-too-famous cruciate ligament rupture...), nor too low so that you don't lose your ski at every turn while skiing. The release value is determined by various factors, such as your level of skiing, weight, age, etc.
This adjustment is located on the front and back of each binding, and looks like a scale. The values correspond to the release value of the binding: the higher the number, the less easily the binding will release the foot in the event of a fall. Be careful with the value you choose, and don't hesitate to seek professional advice.
Use a Phillips screwdriver to move the values by tightening or loosening the compression. Carry out this operation at the front and rear of each bracket as shown in the images below.
The AFNOR (Association Française de NORmalisation) has published a table for determining the tightening value based on various parameters (ISO 11088 standard, 2006).
The first line of the following table corresponds to the length of the sole of the ski boot in millimetres.
If you come across an empty box in the table, take the nearest figure on the same line, except for skiers weighing more than 94 kg, in which case take the nearest value in the size column.
Finally, this setting should be adjusted according to the skier's profile using the following table:
3) On older models of bindings: Compression settings
Once the binding is engaged, you will now see the compression setting. This is an important adjustment, as it allows the binding to follow the flex of the ski as it bends under your feet during turns.
This is usually a yellow indicator that needs to be placed in the middle of the adjustment zone. To do this, move the heel piece a few millimetres forwards or backwards until the desired result is achieved.
If you have any doubts about your settings, don't hesitate to ask an expert for advice by visiting one of the Val Thorens sports shops. Now that you're ready to hit your favourite slopes, all you have to do is enjoy the Val Thorinoise snow!
