Cressi Adult Short Light Swim Fins with Self-Adjustable Comfortable Full Foot Pocket - Perfect for Traveling - Agua Short: Made in Italy

So I purchased these for my brother who is a US men's 7.5 and his girlfriend who is a women's 7.5. He originally bought them as 7/8 US size; 41/42 EU size. But they were loose. Returned to exchange and bought one size down 5.5/6.5 US; 39/40 EU. They fit, but still would not fit snug--if water got in between his heel and fin, it would eventually and gradually slip off. We are no experts on diving/snorkeling fins, but based on experience with rock climbing shoes, we assume it should fit snug for this kind of activity. His girlfriend got a 4/5 US; 37/38 EU and he tried it on and it fit perfectly. It had no give, his got returned for a 4/5 US; 37/38 EU. Quick advice--buy 2 sizes down! They don't fit true to size!This is where the fins really get their good rating: the material on the foot pocket is not a hard rubber, but a silicone-like material that feels amazingly durable, comfortable, lightweight, and flexible, which is where it gets its "self adjusting" feature. They almost mold into the shape of your foot to create a seamless fit. The fins are lightweight overall and he mentioned that they will be very easy to propel himself through the water. He has owned cheaper fins which weigh a lot more and uses more effort to kick. He loves these already.The design and craftsmanship is well-thought out and these will probably last him years to come. He is very excited to use them for snorkeling in Hawaii and this product deserves five stars because of the quality, portability, and durability. The sizing is confusing but the best suggestion is to not be afraid to go down. It will be better to not worry about it coming off while diving or snorkeling. If you are using booties or neoprene socks, going down sizes would not be too big of an issue either. As mentioned, the foot pocket material is very malleable and flexible. One size down would be manageable, two is probably more for a really nice snug fit. It is all personal preference in the end. Great product, but wish there was more descriptions on the sizing!

I don't normally write reviews... mostly because few things impress me enough to take the time but these are AWESOME! I've been diving for over ten years and these are the first fins of this type I've bought and honestly I had low expectations but we're going on a cruise so I needed something I can pack and let me tell you. They are small but mighty and SO comfortable and light! I can seriously move in the water I LOVE THEM!

So I finally got to test these out along with some other equipment like a new mask and snorkel I picked up and these fins fit well they are comfortable and work okay compared to the larger fins I've rented in the past the advantages they have are that they are easier to walk in the disadvantage is you lose surface area to push water and Propel yourself. That being said they still do work well especially for their size. Overall I am pleased with the purchase and I will be using these quite a bit on an upcoming Cruise

Exactly what I wanted, helps in my swimming workout, fits good, help me move through the water faster and have better form

These fins were perfect for me, a strong swimmer who floats easily. I have a wider foot and had enough room. I love the shorter fin and had no problem quickly moving through the water, if desired. I found them quite easy to put them on in the water as well as easy to walk on land. I highly recommend these Cressi's.

A previous buyer helped me understand the sizing, as that has been my big issue before purchasing these. I followed her advice, and they are perfect! I wear a UK size 8 and my feet are wide. I bought the size 7/8 which is 41/42, and even though it is a snug fit, I am sure the next size would have been too loose, which you do not want in a full foot flipper. Returning items from South Africa is too costly to make any mistakes, so I hope this will again help someone else. I love the soft heel area, which makes it easy to put on, and I love the shorter blade area which I think is going to be great for snorkeling. The flipppers arrived in good time. Overall really happy! Cannot wait to get to the coast in November. Thank you!

Using these for doing laps in community pool for exercise: lightweight and just enough fin. After I tried a pair, my spouse bought a pair too and is equally delighted. We use thin lightweight socks with these based on a general tip we read for using swim fins. Very comfortable!

Perfect for snorkeling. Great small size.
