All Happy Socks are high quality socks. Since the cotton is combed before being spun into thread, the short fibres fall out, while the stronger and comfier long fibres stay in. The cotton is then woven in Italian knitting machines of the brand Lonati, famous for their high precision. The machines are computer controlled to ensure exact patterns, while the toe seams are sewn by hand to guarantee perfect fit. The hand linked toe seam ensures that there is no bulging overlap at the toe, but a perfectly smooth seam, making the sock fit your foot like a glove. Produced from the best yarns with handlinked toe. Wash inside out. 80% Combed cotton - 17% Polyamide, 3% Elastane. We currently cannot ship Happy Socks to Canada. We apologize for the inconvenience.
