Booster Straps - Once Again - Page 2

post #31 of 49
I don't get the reason for your post, Atomicman, what am I missing? Certainly the Booster goes under the shell, but I did it with the stock power strap as suggested in another thread. I have thought about getting a Booster, but haven't done it, yet...

ssh, if I read Atomicman's post correctly, he thinks that you will get flex and rebound compared to your current strap, with which you feel no "give" at all.

You have an engineering degree, yes? My metaphor for this device has been that of a 1/4-wave transformer between free space (compressing liner only) and a waveguide (pressure on boot shell). This is why I put a 2-strap Booster on a soft Tecnica boot and a 3-strap Booster on a Fischer 9000. Same weight (195+) and height (6'). I do not miss the 3-strap with the soft boot.

This may seem irrelevant to the dicussion on its own, but : Do you free up your top buckle entirely for powder?

One of my current projects is to replace the instep strap on an XC skate boot with one where the non-velcro-bit is elastic, much like Marker did on their spring gloves.

I suspect Atomicman is reminding us about Skimetrix's recommended placement for
the straps.
Both here and at TGR, a sizable number seems to not get it as to placement;and
then complain that the Booster doe not work.

Thanks Comprex, Absolutely Correct!!!

Isn't this what ssh was asking for thoughts on when his stock powerstrap restricted his flex?

Thanks, John J, Also Correct!

I was looking at getting the 3 srap one for my new boots. I didn't like the $39 price . I have the original 2 strap one installed on my old boots but I think I only paid $15 when I bought it years ago. Anyway, if they do deliver the improved performance indicated I guess the price relative to everything else ski related is in line. I really had to get the Booster strap high up on the tongue to allow my boot cuff to close . I always wanted the Booster Strap to be above the cuff plastic rather than beneath the top cuff buckle plastic.

Sorry, AM, I wasn't clear. I was simply commenting on the incredible difference in performance when I moved the stock strap inside the shell. What I am assuming is that the rebound in the Booster would moderate that somewhat. It seems that there's some agreement on this. Do you agree?

Bootbags can be far more gaperish than carrying boots over the shoulder. They also help breed the nasty rank ass crap that grows in ski boots.

Don't use one, and you can never get one stolen. It also forces you to pack lightly (what doesn't fit in my pockets, helmet on the way from the car, or in the cuff of my boot doesn't come skiing) which has additional theft and security benefits.

Of course, I also don't believe in lodges.

Booster straps are nice, but I vastly prefer the Nordica implementation to the real deal. Not as effective, but much easier to deal with on a daily basis.

So yesterday (still waiting for my booster straps to arrive) i moved my power straps totally inside my shell, it seemed to put me on my heels. when I moved it back outside the shell, still on the cuff partially, but not completely in the shell in the front, this stopped.

Does this make sense? And if so what about all of your suggestions to put the booster strap totally inside the shell? I have tecnica Rival boots and the liner doesn't come up much above the top of the shell.

The booster strap is elastic and therefore flexes with and rebounds with the pressure of your lower leg when it is inside your shell.. Your stock strap has no flex which when inside your shell would increase the resistance to forward pressure. 2 completely different effects.

Hi A'man, that makes sense. But does it make sense that the power strap this way would put me on my heels? What is happening that would create that?

It's pushing your lower leg flush against the back of the boot which is moving your balance point and causes you to put weight on your heels.

Do you have really skinny legs and the boot is more for wider calves?

As Scalce has said, the stock power strap is not letting you flex your ankles. If you have it "TIGHT" inside the shell it is keeping you from rolling forward at the ankles which would put you on your heels. the elastic booster strap should not cause this.

It is likely that when your stock strap is outside of your shell you are not getting as snug a fit against the shell of the boot. Your lower leg is allowed to travel forward until it meets the resistance of the shell. You have moved that point of resistance much closer to your leg by tightening the strap inside your shell. This actually could be a good thing. You just may need to adjust to this new fore/aft balance point. It also may not be good. If you are constantly on your heels and can't get forward or even centered, this would seem to be detrimental to your skiing.

Again, the booster and stock strap work very differently.

But it is fun to experiment!

no my legs fit fairly snug in the boots as it is, but of course I have to clamp down on the top buckle and yank the power strap tight to really get constant shin/tongue contact (now there's a contortion I'd like to see - shin to tongue

Yes it is. And yesterday was my first day on fairly hard pack icy conditions (10th day out.)

Now as far as fun experimenting I'm NOT planning on trying to get my tongue to my shin - particularly not here at work :

Have you ever got a stance and balance alignment?

You may need some boot work to fix some issues.

Like I have a 5 degree heel lift in my left boot which puts my knee 1 degree inside of center and I have a .5 degree shim in my right boot and a 3 degree heel lift which puts my right knee at 0 degrees.

I am slightly bow legged on my right side and my natural balance point is alittle further back so my boot adjustments allow me to stay centered or forward and flex my ankles properly.

Now with the Booster strap I am constantly making shin to tongue contact and can control the tips of the skis no matter what.

It's a nice feeling.

I had custom foot beds made and lots of boot adjustments done by Greg Hoffman at Green Mountain Orthotic Lab last year, so I should be in good shape that way. It wasn't until I tried putting the power strap inside the shell yesterday that I felt out of aligment.

My notes from the alignement say Heel Lift 1'8" B/L and Cant L - 1 degree (whatever that means)

$.02

I have been using Booster Straps for quite a few years. I have always wound up using them inside the cuff tongue...as suggested by Booster Strap....on the outside ...the boot became too flexible. I just bought a new pair of Nordica Beast 12's.......Nordica has licensed the product from Booster Strap....and the new line comes with the Booster Strap as stock. Very nice feature...and quite a nice boot. If you get a chance take..... a look at their setup in a shop.

Shen, now that Nordica parts are available online, I can get either the Booster strap proper or the Front-velcro Nordica (Dobie) B-strap.

I like the Y-profile Nordica B-strap design.

Is there any noticeable performance advantage to having the elastic in front of the boot tongue vs. having it in back?
