Sudoku Tabi Socks
These Sodoku tabi socks are partially solved, so you shouldn't have to stare at your feet too long to complete the puzzles!
Made in Japan.
Though the label says they fit "US women's shoe sizes 6-11and men's shoe sizes 7-11" we found their range was more like US women's shoe size 7-12 and men's 5 to 10. Narrower feet might find the toes a little loose.
