Rating: Perfect Choice for my Budget
Reviewer: Gordon O.  -  View all my reviews
These fins are tough, durable, and seem to be allowing my feet to grow accustomed to them - Im developing callouses where I need them. Theyre extremely inexpensive yet do the job well. I have wide feet and these are ALMOST too narrow. I swim laps in a pool for 30 min 3-5x/week. "Swim" fins, as opposed to snorkel/scuba fins, lack the resistance I need for a good workout. So, I use snorkel/scuba fins. Other Fins Ive used. Ive been wearing out a pair of cheap fins every 18-24 mos. They tend to break down where rubber and plastic are joined. Add to that, prior fins have tended to chafe my little toes. (Ive got wide feet.) Theyve given me blisters and Ive had to tape up my toes before swimming.

Although I havent had a chance to use my fins yet, they were exactly what I was looking for. I had a similar pair that just wore out after 20+ years of use, and the ones I ordered are almost identical. We are spending the month of Oct.in Kauai and I got there fins as they are packable,relatively lightweight. Ill enjoy using them in Kauai for a lot of snorkeling!

Reviewer: Nicole Spisak
I ordered a new set of snorkel fins within a couple of weeks before a trip to Bermuda. At first, I was nervous that they wouldnt fit our that I wouldnt get them in time. I recieved them in plenty of time before my trip, they fit great, they were priced just right. I couldnt ask for a better shopping experience online.

Reviewer: Lori S.
These fins are fantastic and very comfortable. I have not had a chance to go in the water with them, but I did waitress in them for 8 hours on Halloween night!! I received many compliments and my tips were above average thanks to these fins! The company is very easy to work with and very reliable! Due to an error in address, my card was denied and the company contacted me. I put the correct ZIP code and asked them to be shipped for the next day. scuba.com got my fins to me in one day! Scuba.com is great and so are their products!! I would recommend them to anyone!

Questions and Answers for IST Sea Diver Snorkel Fins:


  • Lori:

    Hello, I wear a womans size 7 1/2 shoe. How much would a pair of fins that would fit me weigh? My husband has a wide foot size 11 1/2. Will my husband be comforable in these fins? How long would his fins measure? How much would a pair fins for him weigh? We are traveling to Mexico in May. Our suitcases can only weigh 50lbs and have measurement restrictions. Thank for your time and attention to my questions. Lori

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Lori, the fin length is 18". The size you would need is the IST Sea Diver Snorkel Fins Black Mens 5-7/Womens 6-8 (Small), as for your husband he would need the size IST Sea Diver Snorkel Fins Black Mens 11-13 (XLarge).

  • Patricia:

    Are these fins short enough to fit in a carry-on suitcase? I have several almost new pairs that wont, and I dont want to spend $50 on checked luggage to take fins with me. Also, do they run true to size? I think I ordered a pair from you before that were supposed to be my size but were too small. Thanks!

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Patrica, from the back of the foot pocket to the tip of the fin is 14". So yes it should fit into a carry-on bag. If you would like to place an order or have any other questions please feel free to give us a call at 1.800.347.2822.

  • robin:

    Are these rubber? Ive had a pair of rubber that has lasted me for years and have also had the plastic ones that have broken. Also, why are these not to be used for Scuba? Thanks

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Robin, yes these fins are made of rubber. Also these are a short fin 14" length so they are not designed for scuba diving. These fins work great for swimming laps or snorkeling.

  • Donna:

    I wear size 9 womens- what is the correct size to order? What is the length of the fins? A previous answer said 14", but that seems very short. Pleas confirm

    Bob  (Certified Scuba Instructor at Scuba.com):

    That is correct.

  • Diane:

    One answer says these fins are 14 inches long and another answer says 18 inches. Please clarify.

    Darrick  (Certified Scuba Instructor at Scuba.com):

  • Karin:

    Im looking for fins for a 3 year old child who wears a 9 shoe. Is the size 10 for a young child? Thanks,

    the 4XS size (10-12) is the smallest youth size we carry these fins in. Those are basically toddler/kids size shoe sizes.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Patricia, these are made of rubber.

  • Donna:

    I have purchased the ocean quest full foot fins. They are much longer in length than i expected. Is this type shorter in length? How many inches are the two types in comparison?

  • Clyde:

    I need a childs size 16 fin. What size does it translate to on your chart?

    Bob  (Certified Scuba Instructor at Scuba.com):

    The chart is from the manufacturer, IST. They do not list a child's size 16. They list 12 - 1, then 1-3 in their sizing.

  • Bob:

    Are the socks necessary (I.e., will the fins chafe, without them)? Looking to do some snorkeling, but dont want to wish I had bought the socks.

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Hello, they will help. When I purchased gear for my family I definitely got them the socks for them also.
