Stiffness of Lange RX130 LV in the Cold?

post #1 of 5

Question: How much will the Lange RX130 LVs stiffen up in the cold compared to how they flex at room temperature?

 

Background/Amplifying Info: I currently ski Nordica Doberman 130 Pros (purchased around 2010) but am looking for a softer boot.  I'm no longer a spring chicken (now 36) and the past couple times I've gone out, I've noticed I'm on my heels a lot more and now seem to be fighting my skis at times which I haven't done in the past.  I've been working with a boot fitter on new boots  and we've narrowed it down to either Lange RX130 LVs or Fischer RC4 130s.  I'm leaning towards the Lange's but just want to ensure they wont end up being too stiff and being right back in my current predicament.  At room temperature, the Lange's feel great and are much softer than my current Dobermans but I would like to know how much stiffer they become in the cold.  During the fitting process, I tried on various boots in 120 and the boot fitter said the boots were deforming when I flexed them and that I definitely needed a 130 (they also felt too soft to me).  Are the Lange's (or the Fischer's) going to stiffen up substantially in the cold.  If it's useful, I'm 6'2" and 200 pounds (maybe 205 post holidays).  Thanks for the help.  Cheers.

all boot plastics stiffen in the cold

 

your stats match well for any of the 130's ( short of actually seeing how you ski ) also at 36 you are just a baby :)

 

most of the current crop of 130's available today have been dumbed down compared to the flex of your Nordica Dobi 130 from 2010. Why the industry is following this path, I do not know? marketing strategy 101 to sell more $650 to $750 boots

 

Any of these boots can be fine tuned in their flex by adapting the depth of the "V" in the lower clog

 

your current boots may be packed out and your foot is subtly moving around and that may be contributing to the feeling of getting on your heels and fighting the skis. Try a neoprene tongue shim in your dobi's to shore up the fit and capture the rear foot back in the shell...

I highlighted the interesting part of your post.

 

Rather than stiffness being a problem I think you may have a fore/aft position problem in the boots you now have.  Boots have being coming from the factory with less forward lean, which will bring the knee to a more upright position---if you happen to have a slim leg in these upright boots you may be standing on your heels at transition.  this will sink your hips downward during the loaded part of the turn and get you in the back seat.

 

I think the stiffness of both boots would be similar when cold.

 

By the way, I am 70 yrs old and ski a 130 flex boot, so I think age has little to do with what is going on.

 

Seek out a balance specialist boot fitter and get your boots dialed in.

All boot plastics vary in chemical make up so stiffening can vary between manufactures and models... Most boots will stiffen in cold weather roughly 15-20 percent..

Thanks to everyone for the responses.  

 

Mike-  You are correct on the stance issue.  The Doby's do have a very upright stance (at least compared to what I prefer) and I do have skinnier calves.  I've had the stance adjusted before and while it's much better than what it was out of the factory and very close, it's still a little off.

 

Due to the love/hate relationship I have with my Doby's (amazing fit but my feet turn to icicles when I use it plus the stance issue), I've decided to seek a divorce and bought a pair of Fischer RC4 130's  Cheers and thanks again for the info.
