Bio Naturale Thermo MTX is an ideal footwear for long walks, travel and free time on the coldest days. The upper is soft and well structured and the combination of ripstop nylon and leather gives the shoe a contemporary look without compromising quality. The internal Thinsulate lining combined with our Mer-tex membrane keeps the feet warm and dry and the 100% recyclable PU outer rand protects the shoe from possible abrasions. The midsole is very light and flexible and the Vibram rubber sole ensures maximum traction and stability. A non-elastic lace is provided for a traditional lacing system.
