Medial Tarsal Area (discomfort and pressure)

post #1 of 5
Thread Starter 

Hello Boot Fitting Demi-gods!

 

I have some questions concerning boot fit with my Lange RX 130s (brannock length 27.5).  I am experiencing pressure and discomfort in the medial tarsal area of both feet.  

 

Some background: The shells have been punched-stretched and grinded in the ball of foot area and the upper shells have been ground a bit to make room for my tib/fib ankle bone areas.  Currently, I am using BD Comfort S7 footbeds and I am using the Zipfit Gara liner.  My feet are wide at 110mm, high arches, medium instep, and narrow heels.  I've had boot fitters at The Ski Center (DC), DQ (Mount Laurel, NJ), and Larry at Ski & Bow (Pagosa Springs, CO) help me with these boots.

 

I recently skied WC CO for a week and I experienced a lot of ball of foot pain (burning, numbness, cold toes, etc.).  By the end of the week I could  ski about 2/3rds of the day in the Langes, but would have to ditch them for my Tecnicas that I also brought along.

 

Question:  Is this shell and/or liner pressure in the medial tarsal area causing the intense burning and ultimate numbness of my ball of foot by putting pressure on the posterior tibial nerve or posterior main artery?

 

I plan on skiing Breck and then Utah the end of March.  I would appreciate any courses of action from the fitters here so that I can ski the Lange in relative comfort and not have to wear my bailout boot the Tecnica.

 

Thanks Much!!

Hi Jim,

 

Past feedback from fitters has been described as having limited dorsi flexion of the ankles.  How much (or little) I don't recall.

 

I am trying to think about this in an intuitive sense: how would ankle flexion tie into pressure/discomfort in this particular region?

 

Below, I drew a red oval around the area of my feet where the pressure/discomfort is at.  The area in question is more the upper lateral side of the arch versus bottom of the arch itself.

 

Thanks for your response!

Jim I think is asking questions based on your early description and I'm certain he'll chime in again.  I liked where he was going but then you sent this picture which shows pain in a completely different area of the foot than you described before and in an area different from that which other fitters have worked before.   HHHHHHHHMMMMMMMMMM.

 

If the problem is around the metatarsal heads then I think Jim is on the right track and the problem may be lack of dorsiflexion.

 

From your diagram I think the problem is pressure from the medial side of the boot on your arch and the solution is to shell fit, outline the area of the boot where your navicular and the medial side of your foot contacts the shell when your heel is firmly in the heel pocket and punch that area until there is enough space.

Hi Lou,

 

Thanks much for your response.  I believe things may have gotten a little lost in translation here.  The start of my thread I used the words "medial tarsal" and maybe it was originally interpreted as "metatarsal" or maybe even "metatarsalgia".

 

That being said, the main crux of my question is two-fold:  First, would excessive pressure (in the region I have circled in the graphic) cause the compression of the posterior tibial nerve or posterior main artery causing  second order effects of burning and tingling of the ball of the foot (+ cold toes)?  Two, is this medial region a common place for fitters to stretch and/or punch out the lower shell?  I see all kinds of threads about expanding the forefoot region, the instep region, and the immediate ankle region.  I've not read much at all about midfoot medial issues and associated boot shell work.

 

I know it's not an apples to apples comparison, but when I compare the RX Lange to my Tecnica Ten.2 HVL, the Tecnica has more volume in this medial region (both boots are mondo 27.5 size).  I don't get this same pain and discomfort that I have with the Lange while wearing the Tecnica.  That being said, the Lange has a superior fit in the ankle, heel, and upper cuff areas.  I have way more tactile feel and control in the Langes.  I am sure the Zipfit helps here a lot ;-)

 

Thanks for any guidance you can give!
