I just recieved my pair of spora sub fins. when i ordered them, they told me camo, but when i recieved them, they were a bright green. anyway, im only going in the cold water, and was wondering what you guys use for a neoprene sock? i know a bootie wont fit in there, but a 3mm neoprene sock might be to thin. anyone know of something that i should try out or buy?
