They used to come in light blue too, like the ones being manufactured in the Californian Pacific Molding plant in the above video. I own a pair, which have comfortable foot pockets and blades offering good propulsion. They are available in large sizes to accommodate booties. Oceanways has been making these Cressi Rondine lookalikes since the 1980s, I think.
Thanks for signalling that Oceanways Aquapros remain in production in black.
