An expert-level boot with numerous comfort features, the Belle Pro has a 100 mm last and 105 flex. Along with a heat-moldable liner that’s insulated with Primaloft and fleece, Nordica’s new Custom Cork liner technology uses cork and resin in the liner to form to the contour of the foot through body heat. Bonus features from cork include insulation and lack of compression so it holds its shape. The Belle Pro also has a sculpted cuff and liner to accommodate women’s calves as well as high traction soles.
