I also ski in a Lange 130 LF occasionally. The HR is the first non-Lange that I have owned in 20 years. The forefoot width on the HR would be narrower than the Lange MF but the Lange tapers faster from the met heads toward the rear. The Nordica has slightly more volume and less defined shape in the rear foot. It remains to be seen, but I suspect the HR liner may pack out faster than I would like but for now the fit is great.
