The used adjustable Deep See open heel scuba diving flippers are a reliable and durable choice for water sports enthusiasts. With the brand's reputation for quality, these flippers offer a comfortable and secure fit for scuba diving adventures. Their adjustable design allows for customization to ensure a perfect fit for each individual user, providing added flexibility and comfort during long underwater excursions. Whether for leisurely snorkeling or adrenaline-pumping scuba dives, these flippers are a versatile option for both recreational and professional divers... They both seem to be in good use condition they do have scuffs and scratches throughout as you can see in my photos I didn't see any sort of a size on these but I wear a size 11 and my foot fit easily inside the hole... Please see photos for details..
