CRESSI long fins. I've had these for about 3 months, but I'm selling them because I no longer have an environment to dive in. I usually wear sneakers in size 27 or 27.5 cm. They fit perfectly with fin socks. There are some minor scratches from use, but I think they are in good condition. The blades are replaceable. I will pack them compactly for shipping. Thank you very much. - Brand: CRESSI - Color: Blue - Type: Fins Diving Free diving Spearfishing Snorkeling Long fins Full foot Gara (Model name) Module (Model name) Thank you for looking.
