Great design whether it glows or not. Reminds me of catching them as a kid!!


Love the design on the socks and the weight of the socks is perfect. Seem well constructed and should hold up after many washings.


Love SITM socks, but these do not glow in the dark more than any other pair of socks. They're great as regular socks, so I'm keeping them, but it was definitely disappointing. Don't buy them if you're hoping for any light whatsoever. There's none.


Love them!!! Great material and design!


Love the sock design, but the glow in the dark is hardly visible, after having been in the sunlight for hours. I even tried to 'energize' them under a blacklight first, and the glow was barely visible in a completely dark room at night. Maybe I got a bad batch?
