The human heel naturally forms a 90-degree angle when standing. Most socks are made with a 120-degree heel to simplify production, but this often leaves excess fabric and causes slipping. MUJI’s 90-degree heel wraps the heel neatly, providing a secure fit without constriction.
Inspired by a Czech Grandmother
The idea began with Grandma Růžena from the Czech Republic. Her hand-knitted socks, made for harsh winters, featured a 90-degree heel that fit snugly, stayed in place and offered remarkable comfort. MUJI wanted everyone to enjoy this perfect fit in everyday socks.
MUJI’s Right-Angle Socks are more than socks - they are a pursuit of comfort, simplicity and thoughtful design. Once you try them, you will feel the difference: a sock that truly fits the shape of your foot and feels effortless every day.
