Shell fit technique

post #1 of 3
Thread Starter 

I have a question about the proper way to gauge the dowel method of shell fitting.

I am staring at a lovely set of new Lange 130 RX LV shells. They are in 26.5 mondo (26 shell), which is what I have been in for Technica XT 17's, and my current Nordica Dobermann 130 Pro's. But unlike the Nordica's which had a 305mm sole length, the Lange's have a 306mm. So I was a bit concerned how that might affect (if at all) the interior length.

So I scrounged around the office to find something round could use as a dowel and came across a round highlighter. Actually, a rather  clever tool because it has two "gauges". The bottom is 3/4" in diameter (19.05 mm) and the top of the cap is 11/16" (17.4 mm).

Bare feet go into the shell with big toe just brushing the boot front. Bend at knee with heel down. The wide end (19.05mm) is a no go. I can not even push it through. The narrow end (17.4mm) will go through but not "cleanly." It compresses the skin on my heel as it passes through.

So my conclusion is that I have a fit that is around 15mm, but only if the measurement, as done by those who know, means a true gap which involves no heel distortion to get through. Is that how you guys do it?

By the way, the forefoot makes contact inside and out, with no uncomfortable pressure points.

Given this fit, I am not inclined at all to go to a 25 shell, which, I believe, would be about  .40 inch shorter, if my calculations are right. I am looking for a less constricting fit, but certainly not a sloppy one.

Thoughts? Any other considerations?

Thanks as always,

BTW - the Lange flex seems noticeably more forgiving and stance more upright than my 4-5 year old Dobermann's. And while it is 1mm narrower in the width, the toe box seems more generous. Just what I was looking for.

normally i use the mark 1 human eye ball, i also have a couple of different "sticks" which we use (AAA and AA mag lights, bezel end or handle end)

 

at 15mm shell check moving down a size for some people is an option for most it is not, had you said 20mm then it would be a very doable exercise for a skier skiing a lot, all very difficult to say without seeing your foot in the shell and how the shell shape matches your foot profile

 

the size down will be 10mm shorter ...difficult this mixing imperial and metric lark

 

sounds like the 26 will work just fine, especially as you are looking for a more relaxed fit than your race boot

Much obliged. I should have mentioned that I am a 9.5 US street shoe - so this is one down size, as I understand how these things go.
