These are Fukusuke tabi socks. While they stretch, they don't stretch like regular socks, so they fit properly and are easy to wear. I bought the wrong size, so they are new and unused. Size: 23.5 cm 4 kohaze (fasteners) Material: Outer: Cotton 70% Polyester 24% Polyurethane 6% Lining: Cotton 98% Polyurethane 2% Sole: Cotton 100% Although they are new and unused, they have been stored for a long time, so there may be wrinkles and folds in the packaging. Shipping will be in simple packaging, using recycled materials. They will be folded for shipping. Please ask any questions before purchasing.
