Karsikko Socks are traditionally worked from cuff to toe. After the ribbing, the pattern continues with a simple yet addictive stranded colorwork motif that repeats across both the front and back of the sock. The heel is worked as a classic flap heel using two-stitch colorwork to ensure durability. The sole features an easy two-stitch stranded pattern that strengthens the fabric while helping the foot last longer under heavy wear.
