Thunders Love produces their socks in Portugal, on vintage knitting machines optimized for quality over speed. These machines are 48, 56, or 96 needle, offering an infinite range of color and pattern in each piece. The toes are handlinked, creating a nearly seamless feel. Thunders Love uses only the best inputs - either a hand-picked Egyptian cotton; or a water-free recycled cotton. Both are blended with polyamide and elastane for stretch and durability.
