The water is 67. I definetly don't want to wear booties cuz my feet would be on fire, and I don't have reef walkers.
Unless you are in indo, or on razor sharp reefs in the Caribbean, you don't need em. And even if you did, you would be wearing reef booties, which are completely different than your standard boots. Just Cobblestone, you definitely don't need em. Anything over 60 degrees, them boots gotta go. It's good for your feet too. Walking across cobblestone is an art form. You will mess your ankle up rolling it before you will ever cut your feet. I assumed you were surfing on a reef or cobblestone, I am just saying there aren't any on this coastline that require boots. Boots are for cold water. Period. Walking on reefs is a right of passage. Barefoot, you always squish around on things and wonder, WTF what that I just stepped on. In booties, you just stomp right through it. Its like shedding rubber, you are much more in tune with the water without it.
Oh, cobblestone - that changes everything. I suggest booties for your feet, gloves just in case you scrape the bottom, a helmet for your head, and a life vest if it gets too deep. Hard to get sympathy from Reefscar. No boots.
