I bought these fins for scuba diving and am getting ready to go on a 2 week vacation in Hawaii. Since the person I am with does not dive, I will be snorkeling a lot. I know these fins will "work" but will they tire me out snorkeling. Tusa Zoom Fins discounts on sale Tusa Would I be better to have a different pair. Also curious if people prefer to have the ones like this where you hve to wear booties or just slip on with bare feet.
