These aren't your mother's motherboards. In fact, mom might hardly recognize the sleek rainbow circuits on these geeky knee socks. They are like something out of a psychedelic cyberpunk movie — perfect for coding class, comic cons or just keeping your feet warm on those late nights putting together your dream gaming PC. Fits women's shoe sizes 6 to 10. 65% cotton, 24% nylon, 8% polyester, 3% spandex. Designed at our headquarters in Bellingham, WA and made in Korea.
