Right Angle Socks
In 2006, in the search for the perfect sock, MUJI discovered Czech Grandma Ruzena's knitted right angle socks - and they fitted perfectly. MUJI wanted more people to experience this comfort, but until then, socks were created at a 120 angle, development began and, with that, the world changed ? by 30 degrees. MUJI had to reinvent the entire manufacturing process to mechanise the hand knitting technique. The sock has been so popular that since 2010, it's the only kind of sock that MUJI makes.
