Not too tight
UNIQLO came up with a solution that strikes a perfect balance, which is to apply different knitting techniques on toes and heels. Knitting darts on toes and L-shapes on heels create the ideal fit that's not too tight, not too loose, easy to slip on, and is comfortable. These are the qualities called for in socks.
Anti-odor yarn
on the inside and outside
We use high-quality yarn with a smooth hand-feel on the outside for comfort and texture, and a polyurethane yarn with self-deodorizing feature on the inside for excellent stretch. This unique construction method is effective in suppressing the 3 types of odorous gas given off by feet (ammonia, isovaleric acid, acetic acid).
