Does anyone know if the same shell is used for the Lange RS 130 Low Volume and the Lange RS 130 (regular fit)? I am assuming it is the liner that is different.
I have the Lange XT 130 LV boots, which I believe are the same fit as the low volume RS and RX 130s. Based on my experience, and the fact that a lot of shops seem to only carry the LV model, I think the LV is actually more of a "regular fit," and the other is for a more high volume fit.
Lange RX 130 LV --> the same mold as Lange RS 130 
Lange RX 130 --> the same mold as Lange RS 130 Wide 
shells are made from different material (I think) and different color (duh!)
RS both Shell and Cuff --> Polyether
RS Shell: Polyether, Cuff: Polyurethane
