I hope I'm posting this in the correct place. I dive here in California with a 7mm wetsuit, and I use a pair of Hollis F1 fins. I need to purchase new 7mm boots. Using the Henderson gold core boots right now but those are falling apart. I would like to get something with a nice thick sole. Any of you guys have any suggestions? Anyone diving with F1's right now and have a boot that works great? Thanks for the responses.
