your son having fun
skilife, your son looks like a really neat little guy. I'm glad he likes skiing so much, that you take lots of time to ski with him and that he really wants to ski with you! Cool!
I've been an instructor for 16 years, with 8 of those devoted to teaching kids. I am a Level 3 cert with kids' accreditation. I have a life mission
teaching families now, helping both the kids and their parents to have fun, learn about skiing and really understand each other's capabilities on the hill.
Please do not interpret my straightforward remarks below as disrespectful in any way. I know you love your son very much and want the best for him.
From what I'm seeing and reading, there are several issues going on here.
1) The boots do not fit and flex properly, they are too stiff. A heel wedge will take up some space and perhaps support him but it is not the final answer.
2) A 9 year old boy in his second year of skiing, even if he is skiing 3x a week, should NOT be skiing double blacks unless he has Hermann Maier's genetics. The mechanics he shows in his turns, his size and how he carries his poles all indicate he has been taken on the wrong terrain consistently either by you and/or his instructors. Even if he shows absolutely no fear.
3) Finally, this is a hard one to tell you. I have scrutinized your class video very closely several times. Almost all the kids in this advanced class are skiing in the back seat (except for one). They all are skidding their turns, making Z turn shapes rather than C's. They are skiing too fast for the task and terrain they're on, even the biggest kids whose size and more years of skiing tell me they should be skiing better than they are. Their instructor is skiing too far in front and too much above these kids' abilities to imitate, follow and . I am not a tech weenie with kids by the way. These kids could have lots of fun and develop their skills doing challenging tasks and games in the right places on the mountain.
I know your son has loved these classes and his instructors. Kids' instructors almost always have the best people skills (better than adult instructors, often!). However, often they are more limited in their technical teaching skills and judgment, due to much less experience. They of course want very much though to please both kids and their parents, so they will (in response to both parties' desires) ski kids in places that can hamper development of good skills. I know because I was one, once. Please don't get upset with the kids instructors though, they are doing the best they can.
Your son skis the way he does right now because of all of the above. Those things are our responsibility as adults, not his.
Therefore, as one poster noted, find your son the highest certified, most experienced kid/adult instructor you can and have them take a look.
I advise that you please back off with your comments to him about his stance (I know your comments are loving though
), tell him you're proud of him and just ski with him for the rest of this year. Don't make a big deal about any of it. Race him, but on much less steep slopes. Take him on easy (green) tree trails, little bumps and whoop de doos, in slalom gates for kids, and in the pipe. Try to do as much of this fun stuff as you can and de-emphasize the color runs you guys do (blues should be the hardest). Maybe do one hard one, every three days just because he will probably ask you. Get him to skate a lot more with you (race!) to help him move forward naturally. He already knows how from rollerblading, and also knows that if he gets in the backseat on his blades, he will fall on his butt.
The idea with kids is, we ski with them. Not, they strive to keep up with us or other bigger kids.
At the beginning of next year, get him another lesson with hopefully the same private instructor who will size him up and give you some good advice about what to do next. If, for social reasons your son really wants to ski with the hardest class, well, you make the call about the right thing to do for the long run.
Good luck, skilife. Even though I wrote you a book, your son's stance really isn't a lot to worry about, because time and growth eventually will take care of everything.
