I'm just a civilian, middle of the pack high school racer (lotta years ago), a customer, not very knowledgeable, so please forgive my ignorance here.
Langes just seem to fit me, and I like the flex. X-Max had a flex I didn't like one bit. To me, really noticeable difference. Go figure.
I happen to own and use both the blue Lange RS 130 LV and blue "World Cup Comp race 140" boots, which I had thought were race plugs, with the lace ups and enough major stiffness getting into that I have to do it in the warming hut.
I can say that the WC comp 140s are fun, add something to a race ski, but are like "a race car driving to the library" otherwise. The RS 130 LVs are great too, even on the same race skis. The 140's just add something extra, that I, as a rec skier, enjoy, but don't really have to have. I just happened to luck into a 140 WC Comp pair (at a 2nd hand ski store) that seemed brand new and exactly fit me, for $110 (albeit with some effort to get on and off). They seemed to fit exactly, better than my RS 130s once on my feet. I'm glad I can use them, but that hardly makes the 130s women's boots. Both work well.
Need for a boot fitter? (& the RS 130 does indeed require high heat to punch)
Over the past four or so years, I've ended up with multiple Lange boots, most bought at ski swaps or second hand places (new or near new), but two brand new (but bargains): RX 130 LV from three years ago, and RS 130 LV from last year. The RX 130 had too upright a boot angle for me, so I put a triangle wedge in the heal that put the boot a bit forward, and it feels just right. The RS 130 LV seems to have the same good angle out of the box.
The latter is too short on my left big toe (that foot is a half size larger than my right), but it seems to fit elsewhere just fine. I only notice left big toe pain when skiing my woman's older FIS GS skis (r23, 183), not on rec skis or on master's GS race skis (r18.8, 182?). The master's skis - and others - don't require as much torque or high angle, seems like.
By mid-morning I can feel the big toe burn. Last year my toenail turned black and blue. I've had it punched, but there wasn't enough heat, I was told. So twice the boot went back to original length.
So I can say with some small experience that the RS 130 LV plastic does require higher heat than most boots. (The Christy tech doing the punching said he'd called and verified from Lange that he'd been using too little heat. He'd been afraid to use the amount of heat actually required, for fear of melting the boot by mistake.) I still have to get back and have that boot punched, but it now occurs to me that having Boot Tech nearby would be better. (I live in Denver.) Have to find a good boot fitter, seems like, here in Denver?
