Well, I'm not sure if what I had on would classify as sneakers, but I have a pair of New Balance water shoes, which look like tennis shoes but are made to be entirely submursed in water.
I had worn them with me to a destination I though was going to be a cold water dive and had taken my drysuit as well which has built in boots.
The water was so warm I ended up wearing the NB shoes with a 3mm shorty that happened to be in my boat. I had to use them as I had forgotten to take my neoprene booties, but low and behold they worked as just as well if not better than the neo booties as I felt like they supported my foot a little better. I had to use mine out of a lack of options. Turns out that I liked them enough to do it again.
Best of luck to you!
