Okamoto Kutsushita Supplement Marude Kotatsu Oyasumi Switch Men’s Sleep Socks – Black / Midnight Navy, 24–27 cm

he Okamoto Kutsushita Supplement Marude Kotatsu Oyasumi Switch for Men are specially designed Japanese sleep socks created to keep cold feet comfortably warm while allowing excess heat and moisture to escape naturally through the open toes.

Developed as the men's version of Okamoto's popular Oyasumi Switch series, these socks combine the warmth of the famous Marude Kotatsu line with a larger 24–27 cm fit designed for men's feet.

The distinctive open-toe structure warms the soles, ankles and lower legs without completely enclosing the toes, making the socks particularly suitable for nighttime use.

Open-Toe Design

The toes remain uncovered while the rest of the foot is surrounded by warm knit fabric.

This allows heat and perspiration to escape more easily during sleep, while the sole and ankle areas remain comfortably warm.

It is especially useful for people who find ordinary thick socks too enclosed or stuffy in bed.
