Glymnis Adjustable Swim Fins for Adults and Kids, Short Diving Fins for Diving Swimming Snorkeling (Black/Yellow, S/MD)

["Adjustable Design] Snorkel fins have an open heel design and adjustable strap design. The adjustable buckle provides more options for different foot sizes. The open heel design allows small pebbles and gravel to automatically fall off. The release buckle maintains the length of the strap you adjusted so you don't have to readjust it every time you use the strap","[Smooth Lines] Snorkel fins have a sense of smooth lines. Short and powerful fins provide good propulsion, reduce signs of foot fatigue, and prevent cramps. The droplet-like mesh on the surface and the open toe design can prevent water from accumulating in the fins, preventing excessive foot strain","[High-Quality Material] Using high-quality PP + TPR material, it is not deformed, lightweight, corrosion-resistant, and has a long service life. Even if you wear it barefoot, your feet will not be hurt. It can also be used with socks and diving boots (Note: When wearing it with socks or diving boots, please choose one size larger)","[Easy to Carry] Each pair of swim fins comes with a mesh bag for your convenience. There is a holder inside the fin. Please remove it before use. After use, you can insert the holder back into the fin to maintain the fin's original shape and avoid deformations","[Customer Service] Package includes: a pair of snorkel fins, a storage bag.
