Tecnica Mach1 130 LV

post #1 of 12
Thread Starter 
Quick question - moved into this she'll from Patron Pro, same size 27.5 (6-8mm) shell fit. About 10 days on them (shift mid-season) and love the way they feel and ski.

Canted -1 on left and +1.5 right, w/ instaprint footbed. Small styloid grind both sides. Stock CAS liner vs Zipfit Gara in Nordica's.

Started to develop a bit of pain on both feet - left worse - indicated on picture. Pain is when standing up off lift and when boot flexed higher edge angles. Regular bootfitter out testing boots when I was in CO so just sucked it up. Any thoughts on how to perhaps fix easily or just wait until he is back next year. Would like to get a couple late season Spring.


days in

Thanks

Pull the liner insert your foot in liner.  Is the edge of the tongue causing the problem?

^ Yes Lou - that seems to be the deal.  Hard plastic of the tongue (inside edge) generally lines up with where the pain is.  Assume there is some remedy for this?  Possible to DIY?

On a tongue liner a hot hair dryer will soften that area (hard plastic of tongue) and you can flatten out the curl a bit there. That will often relieve that pressure point.

 

Heat the area of the hard plastic on the tongue until it feels soft and pliable don't concentrate the heat at one spot but move the hair drier around. I recommend you wear some good work gloves to protect your fingers from the heat, and flatten out the curl of the tongue down in that area. Hold it that way until it cools or if you have a large enough clamp, you can gently clamp it flat. Don't squish it or you will compress the padding on the tongue which is not your goal. you just want to flatten out the curl of the hard plastic.

OK, it does sound as it the tongue is causing the problem and it isn't unusual.  What dchan said will probably fix the problem.  If it doesn't it is possible to have the plastic in the area ground thinner to soften it.

Thanks all. Will give it a go.

I think this is indeed due to the tongue. I flattened it out as suggested and it was "better" but still painful at times. Seems it has to do with where it is. I have kind of a thick instep and with liner out - the sides of the liner barely overlap the tongue. It seemed if I stopped every 30 minutes or so and pushed the tongue down - it felt better for a bit. I'm sure this is a simple deal w/ proper bootfitter. Season done for me in guessing so next Fall will redo.

So you've determined what the problem is, but it sounds as if unbending it won't resolve the problem.  Best solution will turn out to be cutting the tongue back several mms in the problem area.

ankle dorsiflexion? got any? too much?

 

it seems to me that you are chasing the symptom not the root cause.

 

that red circle looks like it is on the tendon, which is directly affected by ankle dorsiflexion. the answer is in ramp angle, forward lean, and flex.

^ thanks - it is on the tendon (both left and right foot, left being more painful).  I can lift my toes off the floor about 1 3/8 inches under the ball of my foot when seated (tib/fib @ 90 degrees).  I did throw the spoilers in the back of liner on this shell.

that tendon fires for some people when it is overflexed and or if there is some instability in the foot that that causes your foot to adapt to gain grip the snow. perhaps that is why the pain/pressure is cyclical.

 

ask yourself the question - what effect on the tendon firing does changing the equation of ramp angle and forward lean have? you said that you put the FL lean wedge in...why? what problem were you attempting to solve with the FL wedge? 

 

see if you can figure out what action, either dorsi flexion or plantar flexion causes the tendon to pop out? 

 

reducing the movement that gets the tendon to pop should be the priority. then transfer that knowledge to the ramp angle/forward learn formula to keep that tending stable while skiing.

 

if all that fails, you can always try to root around in there and cut or grind on the tongue/liner or add padding to the tongue to float the tendon in a channel that spreads out the load. but as earlier stated i strongly recommend that you quite down the source versus treating the symptom. as an aside figuring out the ramp/FL position will carry a side benefit of improving your stance and balance as well as getting rid of the pain.

Foot feels solidly "locked" in the boot. I've had trouble in the past with heel movement and the like, but not here. Could it be "locked" in the wrong position?

I skied the boots w/ and w/o spoiler - the with "felt" better and also took up some room in the cuff.  I can try w/o and route the booster under the cuff flaps to achieve the same volume take up <- had that setup with my Patron Pros (actually followed your youtube video ginding shell cuff down for a path on strap)

Would think dorsi since I feel it more as speed and angles increase on the downhill ski - don't feel it just standing in boots

Appreciate your advice/direction in thinking through this - seems logical path and know diagnosing boot fit over interwebs is a challenge at best.  Maybe I pop up to your place next Fall. I'm in the Bay area at least once a month - not a big deal to add on.a side trip up to Truckee.

^thanks for your thoughts on this.  Doesn't shut me down, but confident it can be resolved w/ correct approach..
