CB Japan tutum Oyasumi Warm Sleep Socks – Open Toe Night Socks, 4 Colors, 23–25 cm

The CB Japan tutum Oyasumi Warm Sleep Socks are specially designed nighttime socks created for people whose feet feel cold in bed but who find ordinary socks too warm, stuffy or restrictive during sleep.

Their distinctive open-toe design gently surrounds the ankles, heels and lower legs while leaving the toes uncovered, allowing excess heat and moisture to escape more easily throughout the night.

Combined with a wide, soft ribbed opening and a relaxed fit around the calves, the socks are designed to provide cozy warmth without excessive tightness.

Available in four soft two-tone color combinations, they bring both practical comfort and a relaxed Japanese roomwear aesthetic to your bedtime routine.

Designed Specifically for Sleeping

These are not simply ordinary room socks.

The construction was developed specifically around common nighttime discomforts such as:

• Cold feet when getting into bed
• Excessive warmth inside ordinary socks
• Sweaty or stuffy toes
• Tight sock openings around the calves
• Uncomfortable pressure while sleeping

By warming the ankle and foot area while keeping the toes open, the design balances warmth with breathability.

Open-Toe Design for Better Ventilation

The front of the sock leaves the toes exposed.

This allows heat and perspiration to escape instead of becoming trapped around the toes throughout the night.

The open-toe construction is especially useful for people who like the warmth of socks but do not enjoy having their toes completely enclosed while sleeping.

Soft Acrylic-Blend Knit

The socks are made from:

• 68% Acrylic
• 31% Polyester
• 1% Polyurethane

The acrylic-rich construction provides a soft, warm feel suitable for cold-weather roomwear, while polyester and polyurethane contribute durability and stretch.
