Hi guys: Self grinding my boots,....comments?

post #1 of 19
Thread Starter 
Hi all, especially to boot experts,

I want to grind my boots. Rossignol R2005 ZB/ZB.

Size 7 (300 mm). I need to grind a millimeter or two in some areas.
Got tricks to safely open that shell, so I can work the Dremel tool around the big toe, and "bunion" area ?

....And please, hold the "leave this to Master boot fitters" comments !!! .

Thanks all,

Dad

I suggest that you leave this up to a "recommended" bootfitter instead of a "master" bootfitter.

Taking off the upper cuff may help, but there are no real tricks to opening up the shell without a spreader. You will need the shell in a stable (ie..workable) position with lots of light. Remember eye protection too!

Good Luck, we all have to do it once for the first time, mind those fingers!!!!

Think I got my answer ( on the spreader device) from one of the boot specialist here (got the picture from his website). That's what I needed to picture. Thanks all. And, yes, I will be wearing glasses ...

don't know what you will be using as a spreader, but the best one I have found is simply two vise grips clamped onto the shell flaps over the instep area. Pull each side open and hold in position with chain, rope etc.

Yeah Lou,
I thought about using a "duck bill" type vise grip, or small wood clamps that can be reversed, and opened with the action of a " worm" (hope this reads correct, had to use the translator for this one...). Will go to my girlfriend's grandfather (he's a wood worker, got all the tools ) this week and see what I can do. Will keep you posted.
Thanks again all,

Dad

just also be wary of the tools you use inside the boot, ideally the burr you use should be 1" in diameter, it is pretty easy to go through a boot if you use smaller tight radius bits as they can dig in to the plastic and bite... unless you have a flexible frive on your dremmel you will struggel to get into the toe box of the boot

good luck

Sometimes a punch is better than a grind (sounds dirty, but it's not ).

jdistefa,

Can you develop on that, please?
Almost everybody told me that punching is very likely to ruin the shape of the shell...

LOL... who is telling you that? Are you trying to preserve the stock shape of the shell for aesthetic purposes, or help customize it to the shape of your foot ?

There are plenty of indications to punch the shell - for bony prominences and for function (i.e. navicular ROM).

If you need more than 0.5-2mm of room, IMO you should punch.

Try punching a Rossignol plug R2005 ZB/ZB in the ankle/navicular area and you will probable get good results. If your problem exists in the first through sixth toe area/ first met area, than imo, you will have a better chance with grinding. The heel area will also be a problem punching area, a grind will work better.

It's more to customize the shape of the foot.
Nothing to change around the ankle.
I've seen boots so deformed, there was a 1/3" gap under the sole (shaped like an "n") after the punch machine had done it's work (to make room for the big toe) :...I don't want that to happen, plus, the local store guy showed me how he worked on a pair he was working on... I don't want my boots to be like that either....:

I agree....

I usually grind heels and if I'm dealing with a plug or area of greater wall thickness, I will often grind first and then punch.

However, I think that most medial surface fitting/contouring (i.e. 1st mtp, navicular, medial mall) can be handled better by skilled punching/shaping of the shell.

Having access to a big-ass Scott press made by Keyser tools (no affiliation) helps!

We do a lot of grinding, but a whole lot more punching. Lots, lots, lots more.

I don't know what machine you guys use, the store near where I live uses a Salomon (branded). Frightening...

I chose the Rossignol boot because I have a medium narrow instep, and, I would say, "normal width" foot. Everything is in the right place, it's just I need to make room, a millimeter or two where the shape of the shell is not exactly the same as my foot. I tell you, this boot is tight ( I have about 6 mm to spare (in lenght) inside the shell, with my right foot. The left one has a full 12 mm). But a size bigger would end up too big. I know, I have the size 8, use it to "play" with the kids...

Went to the hardware store today, but,....not convincing...

Will probably use shaped 2X4's as spreaders (had a practice shot today...not bad..., but got caught by sunset...)

Well, I spent the morning (I have to say I'm recovering from surgery, so I'm at home for the next month) grinding whatever material I wanted off...

Results: Good, I'm satisfied with the comfort around the "abductor hallucis" (I did a little research for those terms guys ...), because I'm pretty flat "footed".
Made enough room so the metatarsal joint of the little toe is fine now...

...But!!!....I have to admit, jdistefa and Lou were right with that one...

...With the bony prominence of my big toe metatarsal joint area, I think I will need punching after all that work( I took almost 3 mm off...). The foot is still getting numb after only a couple minutes....
...I didn't try to work in the toebox area, ...my burr is too small (don't want to ruin anything).

So that brings me a question: Can you make room (in lenght) in the toebox area with a "gentle" punch ?

Thanks all,


Dad

Sometimes by grinding a pocket for the 1st met head, it moves the great toe harder against the shell.

Yes, A gentle punch can be done to square off the toe box on the big toe side. It is not the easiest punch for a do it your selfer.

The toe shape of the race boot that you are working with "swings" fairly quickly from the widest point of the 1st met head towards the center line of the boot. You will need to "square off" the shell in front of the first met head forward to the tip of the boot. You want to make sure that you fill in the toe box with material that will not compress above the toes so that you do not "collapse" the toe box on top of the toes as you expand it wider. Also now that you have a grind for the first met head, you need to be careful that you do not distort that area when you are heating and stretching close by.

UPDATE:
I ground some more material on the lateral side, thus making room for my big toe(s), especially right foot.
Now the boots are 90 % perfect.
I will still need to make a little room at the toe pocket "ceiling"...and a tiny little room at the very front, where the big toe is...
Wearing the boots everyday in the house (I'm at home folks....recovering from surgery...) is helping finding the pressure spots...
I saw a boot spreader on the Net made out of a "caulking gun ". Pretty easy and cheap to make.
Will probably try this...
