These wool black shoes are designed to envelope your feet in warm snug comfort. The Shoe Charcoal is made of natural wool and avoids unnecessary chemicals and uses only colours that are free of heavy metals and toxic dyes. Traditional felting craftsmanship and a sole of semi-vegetable tanned calfskin allows these slippers to adjust to your foot shape after just a few uses, making them more comfortable with each wear. These shoes are best worn sockless as the wool's breathable moisture-wicking properties ensure less perspiration and a natural odor-free environment while the unique felting process removes the itch of wool keeping feet in blissful warm comfort. Inside, a double layer felted wool insole provides cushioning and enhanced durability. A lightweight flexible leather outsole delivers secure traction and ensures no static electricity is generated when worn.
