I purchased these shoes to be used as my primary dive boot. I've now dove them in South Florida a total of 22 times across two trips in various conditions and they are amazing both in and out of the water. Its been nice walking on rocks and climbing over things, getting gear from the car to the boat, without banging toes. Once on the boat, I was impressed with how grippy the soles are as dive boat decks tend to get slippery with flip flops and bare feet. These shoes are a much safer option in my opinion. They fit great in my fin pockets but I did need to test fit before buying fins and ended up sizing up my fins to accommodate which is pretty common. I wear them with a thin neoprene sock and they are very comfortable. I highly recommend these for serious divers!
