 Poster: A snowHead
|
I'm an agressive skier, and I've got a bit of weight behind me as well. At the moment, at the end of a days skiing, I get some swelling at the front of my ankle, dorsal aspect of my foot, around the anterior edge of the tibio-talar joint. When I'm skiing it feels as if that although my foot is held firmly in place in the shoe of the boot without heel lift, my lower leg is collapsing forward in the boot cuff.
My boots are five years old now, so I think that I need some new ones, but is this suggestive that I might get on better with a stiffer boot?

Kramer, It could point towards a stiffer boot, but also fatigue or wrong in volume.

Well, the person's real but it's just a made up name, see?

SMALLZOOKEEPER, it's not fatigue. It's when I'm driving forward and flexing my ankles in my boots, it just doesn't feel as if there is enough support at the front.

so, IMVHO, your not short of money, your boots are 5 years old, you have improved a fair bit since then, and you want to defend your crown at the EOSB.
Sorry, what was the question again

Kramer,
I think SMALLZOOKEEPER, could mean boot fatigue rather than user fatigue?

In that case it could well be. I've had to tighten all the clips on them considerably for the past couple of trips. So time for some new one then.

Wear The Fox Hat, No, not ours. There are other shops whom do seem suspisiously fond of such boots, no matter what shape the foot.

And love to help out and answer questions and of course, read each other's snow reports.

If you are Irish and want to remain neutral, then yes!

You know it makes sense.

Kramer, You could pretend to be a beginner then hire some for a day....your old boots will seem fine after that.

I read somewhere that the difference in stiffness between a softer boot and a stiffer boot is in the lateral flex rather than fore/aft.
Does anyone know if this is true and, if so, how much difference in fore/aft flex is there?
Also, how is it measured?
The guy from Nordica at the Birmingham Show told me that the Nordica and Salomon boots' stiffness ratings were compatible but other manufacturers ratings were on a different scale...just to confuse things further.

hellfiresliding, The Standard test is now being implemented for all brands. The Flex test is as follows. The Boot is put into a temperature controled envirionment, 22 degrees. the boot is closed around a mechanical leg, clips set at medium setting with the stock liner. The Boot is then flexed through 10degrees(angle), 30,000 times. The energy used to complete the test is then divided by 30,000 times. The resistance to this energy is calculated in Newtons and the flex rating is given, ie 130 etc. Differing types of plastic will offer different resitancies at different temperatures. Polypropylene being worst effected, Poly-Ester less so and Poly-Ether marginally. A Poly-Ester ski boot will become 5 times stiffer between +15 degrees and -15 degrees (average), making a boot with a flex resistance of 100kn, 500kn!
Flex does not accomodate weight, speed traveled or height and therefore is subjective. Do not use this as a guide as to your ability or needs. A big fat beginnner may need a stiffer boot than a light weight expert.

SMALLZOOKEEPER, why have they chosen such a high temp (22deg) to do the test at if the plastics are affected so much by the cold?
Wouldn't it be more relevant to do the testing at a temp that's more likely to be skied in?

FenlandSkier, at a guess, it's cause it's easier to keep a room heated to 22C at any time of the year, than it is to keep it cooled to 0.

FenlandSkier, Yes, i guess. But i belive it is optimum temp for the elasticity of the plastics. Plastics are/have not yet been made specifically for ski boots, those that have been made with cold temperatures in mind are too expensive for our tiny market. There are the equivelent of 60 pairs of ski boots in a Peugeot 106! So plastics come expensive! The other reason is that you test them and try them at room temperature, so the plastic needs some give and resistance, here the plastic is at it's optimum temperature and so pleases the user.

SMALLZOOKEEPER, Just read your note about boot testing again.....does the mechanical leg arrangement flex the boot both laterally and fore aft?
Also, I wonder how things like Salomon Xwaves will be rated since they claim to have different stiffness on the outside and inside faces with that honeycomb pattern.

hellfiresliding, Resistance is tested Fore AFT. Lateral stiffness will be at almost 100%. The Space frame of which you speak is a Clog modification alowing lower resistance to the uphill ski edge. Ski boots will not be rated laterally as high speed edge transmission can change from turn to turn on any skier. Cuff alignment can be used to effect transmission and response.
