Depends on the application

Older wetsuits were not "waterproof" but the theory was that the water that seeped through would prevent further water from getting in and your body would warm the water that was there and form a kind of barrier. I don't know if that was the real principle or not but I did windsurf in cold wind/water in comfort. The booties that we wore were of the same material. I am certain that material is better today (I have surfing wetsuits that are very good at keeping me warm). But it can't hurt to ask when the foot ware was made.
