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.
