Shoes purchased for the harsh winter that we pass. The interior is lined in synthetic fur. Leather Exterior. Only downside: the laces are too short. One difficulty in making laces (only 10cms on each side). The molding of the sole is not perfect and has some shoe rubber streaks (mold problem?). She is airtight, fairly resistant to cold, very well to the rain. comfort is also the appointment. Satisfied with the purchase. Quality shoes
