Just a caution on attaching your leash to the footstrap of your ski. In two different ski's from two manufacturers both using the same aluminium sliding bracket with stainless screws holding the footstrap to the slide mechanism, the screws have pulled out of the aluminium, once when pulling hard back with my feet in a wave the other when I lifted the ski by the footstrap during a portage in a race. I found in both cases the screws could only be turned a few turns once the thread engaged so there is not a lot of thread holding them in place. Now I attached my leash to the carry handle of the ski and also loop it through the bungy cord beside it as well as a redundancy measure.
Perhaps manufacturers should be advising us which point of the ski is suitable when it's not obvious or we as a community should demand that a leg leash attachment point be a mandatory safety feature of skis. Even as I write this though I know that they would probably be thinking if they were to provide one and market it as such and a failure resulted in injury or death they may find themselves in legal trouble
