DIY 雪靴鞋墊

[lelo]

昨天本來要開始做軟墊的，不過想了一想，也許根本不用做足弓襯墊，就根據大腳趾跟腳根大略畫了兩塊墊片，如下圖：



用膠帶固定，試穿之後，發現也能矯正過來，足弓也不會不舒服，試著做 up & down 的蹲起動作，膝蓋調到腳掌正上方之後，真的省力很多，回去再拍拍跟以前墊信用卡的對照圖。

要做 canting，我看普通雪靴只要在鞋裏的鞋墊下工夫就行了，根本不須磨鞋底，磨鞋底是那種幾乎沒襯墊的競賽級雪靴才需要做的事 ....

對照圖，從膝蓋跟雪靴的相對位置，可以看到有調整過去 ...



左邊四張是鞋底墊信用卡的，雖然很難看出來，但放大後，膝蓋跟雪靴的相對位置確實有改變，最右邊一張則是墊雪靴內的鞋墊。

照片要這樣畫紅線，是因為墊信用卡時雪靴會傾斜，沒辦法從膝蓋間距或雪靴位置看出改變。

耶，不錯耶，真的拉直了，真神奇，不過至今我還是想不透為何內側墊高，可以使O型腿拉直？ :p rimitives (16):

嗯，我覺得最後你墊的腳內側前後兩塊反而比原來的構想更讚，至少如果改以較硬的軟墊，應該會蠻舒服的，也會有助你更易於做腳軸心的軸轉。最後如兩腳都完成，方便拍張照片來看看嗎？另外，原來這一張能不能縮小一點呢？我只能看到左邊四張照片，右邊第一張只有把圖檔下戴下來才看得到，我一開始還看不懂你的解釋，最後只好猜這張照片有五張圖，果然下戴後猜對了。:wawavillage (41):

最後小小建議，都做好後，一定要穿著走兩個小時以上來確定是否有不適感，其二就是下次真的要帶去滑的話，一定要把BINDING調小一點，這樣可以更確保膝蓋的安全。 nion (47):

PS.鞋帶都有扣緊嗎？

圖片我搞錯了！我是對著鏡子拍的，所以圖片應該水平翻轉一次才對，但最右邊一張我忘了做這個動作，所以左右腿搞混了！

我剛剛重畫線，卻發現膝蓋並沒調回來，雖然我感覺有調回來了，我還要研究一下，是畫線的方法錯誤，還是拍照的誤差，還是我根本感覺錯了 ....

我搞迷糊了...

如果是做右腳的動作，這跟是不是對鏡子拍沒關係吧？

那就都重拍一張，一張是沒墊，一張是墊信用卡，一張是高腳墊，但我會建議最好是兩腳都一起墊，這樣同時站，一張輕鬆站好，一張做動作。最後就是鞋扣要綁好，因為你的照片看起來鞋扣鬆鬆的。你覺得如何呢？:face (341):

午休時再請我同事拍了幾張，這次地上畫參考線讓雪靴對準，旁邊設鉛垂線，雪靴穿五分鐘，確定扣環扣到三格以上，單腳站立，重心放前腳掌，拍出的照片確實有矯正，不過很輕微，上面的條件有誤差，就看不出來了 ....

不過我同事拍照技術實在欠佳，照片都糊掉了！我明早把相機架在三角架上再重拍，晚上腳會水腫，不好穿雪靴 ....

[lelo]

重拍一組照片，這次相機架在三腳架上，並使用快門線，雪靴拍照時對齊地上的格線，旁邊設鉛垂線，確定扣緊雪靴，站立時重心擺在前腳掌上 ...

如下圖，左邊白色繩子是鉛垂線，兩張照片左邊是沒加鞋墊的，右邊是有加鞋墊的，可以看出右邊的紅線離雪靴較近 ...



至於為什麼加鞋墊能矯正過來，我想原因很簡單，就是我這雙怪腿，本來就讓雪靴變形了，加上鞋墊後讓變形減少，自然就矯正過來 ....

[norman]

我借你的照片再加工一下，以下圖來看，應該有更加改善些。我覺得你加了墊後，少說也有0修正一兩度左右吧？

另外我再多畫一張我的想像圖，不知O型腳就是有這樣類似的問題呢？:face (341):

[lelo]

你的圖很清楚喔！

確實我平常站立時，腳掌是外翻的，塞進"正常人"的雪靴後，腳掌沒辦法外翻，就變成中間那張圖那樣了 ...

鞋底加鞋墊後，等於把鞋筒往外側擠，這樣就跟做 canting 一樣了 ....
我前面說的可能錯了，是加了鞋墊後才把雪靴擠變形，不是在加之前！

另外圖放大一點啦！看你的圖得用放大鏡耶 ...

我放這麼大張，應該看得很清楚了吧？:face (52):

話說回來，如果你的腳真的如中間那張圖的話，那你要edging確實比一般人較難一些，因為你的上半身要調協下半身的重心，會有點偏差，雖然加強技術可以補強，但確如你所說的，兩膝會有點疊在一起。我覺得如果加墊可以改善這問題的話，確實應該好好研究做出一個好墊出來。 :p rimitives (16):

還好我沒有你這樣的問題。:20070218175808:

還好我沒有你這樣的問題。

好像還有足弓支撐問題也要注意一下，我滑一滑，有時會有好像足弓都壓平了的感覺，我要開始來做足弓支稱軟墊，看看感覺如何 ...

Brother Lelo,

I seen the photo of your creation.....that is perfect.......
Just the two pieces of canting platic to the boot board then you will be fine.
One suggestion is that the toe piece(for the front part), make it longer to extend the canting support towards the mid part of the foot.......If you want to be better,make a piece that is the whole lenght of the boot boeard.

The photos show that you are neutral with the canting in. Your center of your knee fall inlines with the second met-head(the second toe joint) and that is perfect....

I do not think you need to modify the sole of the boot....

Good job,......Well done

呼！終於做對一件事 ...

墊片延長我會再找時間搞，謝謝 stillskiing 兄！

Bother Lelo,

Can you tell me what are you try to achieve or improve in your skiing?
Please write in simple sentences......my Chinese is NOT,,,,that good...
May be I can offer you some simple ideas to change your skiing.
When I was an instructor, many years ago, I learn lots of little ideas to help skiers, Sometimes these little ideas will help a lots.

Cheers,

SS

Here is a very good example that shaving or canting the boot sole is NOT THE ONLY solution.
As I have said many time before, Alignment of the foot with FootBeds and internal FB posting is very effective. The end result is just as good, for the most of us. Racers are a totally different breed of skiers..........And I don't think we are all at that level yet; I am speaking for my self, off course. There are some better skier out there in this forum that may benifit from the sole canting.

Happy Carving......

Bother Lelo,

我想照影片裏頭這樣滑，但我發覺影片裏，用窄站姿加雙腿平行來 edge 的方式，
我做不到 ...

我加一段英文好了，希望沒搞錯 ...

I would like ski like the movie, but I found the edge method teached in the movie with narrow stance and parallel shin,I can't do as it.

Brother Lelo,

I saw the photos of what you are trying to do; a self DIY footbed.......That is very creative and highly engineered. You are ONE SMART person. You should be an engineer, if not that you are one already.

If I ever decided to take on an apprentice, you would be my first CHOICE.....GOOD SHOW.

Now for your skiing.
First, my "worthless" opinion on the short video. That skier's stance is too NARROW.
For you, my suggestion is to ski in a wider stance.
Then, be good at carving big wide turns. Be comfortable at all speed and snow condition. Learn to use the different part of the ski...tip, the waist and the tail. Learn to shift the weight forward then center and the heel. You need to FEEL the preasure and the reaction form the ski. Learn to put presure to all parts of your ski boot.
The next step is to gradually decrease the radius of your turns.
If you can NOT carve big turns.....you are NOT going to do tight turns; especailly in mogals

I hope this will give you some ideas of how to use th eedges and controll the turns.

stillskiing 兄過獎了！我確實是個從控制工程轉行的軟體工程師，做這個做的很順手，不過是平常愛搞 DIY 而已 ...
如果不是英文太爛，真想跨海跟 stillskiing 兄學學 ...

站姿的事我會想想，謝謝 stillskiing 兄！

Brother Lelo,

I am doing the same project to my own boot. I will post a photo log.
