With new skiis- how important is flex?

post #1 of 5
Thread Starter 

Found an interesting couple videos - http://skiherenow.blogspot.com/p/chapters-1-to-6_27.html  

that got me wondering just how important is the ability ot pressure the tips?

 

One thing, on the video,  that hit me like a brick was the example of boots that are too stiff (he demonstrates with a chair) and how that forces  skier into the back seat.    As this is my chronic problem I am now wondering if the boots are part of my problem and I should move to a softer boot?

 

Thoughts on flex?

couldn't even get two minutes into the "Overview" without wanting to bash my head into the wall.  Was afraid to listen further.  It can only get worse since there is no understanding of the most basic concept of binding position.  The AFD is not the centre of the running surface automatically.  It is the centre of the running surface if the manufacturer chose to mount their bindings so far back that turning was removed from the sport.  Do not pay any attention to this site.

 

That said to stiff a boot could keep you in the back seat but probably not as likely to as incorrect binding position or too much boot ramp or binding delta.

there is  a lot of good historical information in these videos. they sure could get you thinking about a lot of things.

 

focusing in on one discussion without knowing anything about you, your skiing, your equipment, etc, is not a great way to begin discussion about boot flex.

 

anywhere close to where you ski, is there an expert boot fitter, or on hill "boot guru" that you could access to help you on a guided tour to better equipment set-up?

 

that would be a great place for you to pose your questions.

Appreciate the response.  I live in Louisville Kentucky,  our hill has 300 feet of vertical and nearest expert fitter would be Chicago  (Viking, where i got current boots) or St Louis.   I am jealous of all those who live in major ski areas!   maybe in retirement....

The responses so far have covered several aspects involved in flexing a ski boot.  the primary action that flexes a boot is having your center of mass positioned correctly so that as you flex and extend you hover just forward of the boot sole center.  this will cause "G" forces to push downward and forward on the boot shell.

 

Lou is correct: having your bindings and boot sole center positioned correctly is important.  Check out a Marker "schizo" binding, you can move fore aft with that one out on the hill and find the sweet spot---might be an option--- just saying.

 

Binding delta plays into the mix,  boot sole length.

 

boot board angle plays a part

 

boot forward lean is involved

 

the size of your calf muscles will also determine where you hover over the boot sole.

 

If you have slim calves and are in a boot that is more upright you will stand on your heels at transition---G forces will push your butt downward behind your heels and the boot will seem to stiff.  Your dorsiflexors aren't strong enough to overcome the loading at 2 to 3 "G's.

 

If you have large calves and too much forward lean---upward movement (extension)  will push the calf muscle back into the shell and load the tail of the ski at transition.  Your knees will still be too far forward and the loading of the calf is not the direction the leg needs to move in to flex a boot---it will seem like you can't flex the boot.

 

So----what is the circumference of your calves at the top of the liner?

 

How much difference between the height of the binding toed piece and hell piece where the boot sits on the binding (delta angle). also boot sole length?

 

how much forward lean in the boot---put a carpenters square behind the boot heel and measure to the liner at the top of the shell.
