US Swim Divers Fitness Fins

I really wanted to like these US Swim Divers Fitness Fins. I needed a size 11 short fin for long distance endurance swimming in a harness in my pool year-round. I did not need a fin that was too buoyant and would make me lazy in my kicking.I compared the yellow and black Phantom Aquatics Speed Sport Adjustable Snorkeling Fins L/XL (size 9-13); the US Swim Divers Grey and Black Large Fitness Fins; the black and yellow Cressi Palau Short Snorkeling Fins size LG--XLG; the SEAC Black (Large 9.5 --11) Fins with the fixed heal strap and open heel; and the TYR BP Burner Fins LG (size 11 -- Blue & Black).First off I had to send back the large SEAC's and large TYR EP Burner's to get the XL size. Both of them were painfully tight on my size 11 feet.The worst first. The yellow and black Phantom Aquatics Speed Sport Adjustable Snorkeling Fins L/XL (size 9-13) are for snorkeling and not for training of any kind. The boot and heel strap are amazingly comfortable and strong, but the composite fin is too long and whippy for training in either a pool or open water. I would not even want to do kick sets with these. I personally would not even want to use these for snorkeling because I would always be waiting for the tips of my fins to catch up to what I was trying to do in the water to position myself for snorkeling/sightseeing.The disappointment next. The U.S. Swim Divers Large Fitness Fins had an open heel which I generally prefer because I wear different booties during the 12 months of the year. The length of the boot was perfect, the heel strap was strong, easily adjusted, and comfortable, and the boots felt really comfortable in shape and foot support EXCEPT for the constant pressure on the knuckle of the little toe on each foot. I'm absolutely a typical size 11, but they hurt my foot, and if you have a slightly thicker or wider size 10.5--11 foot go up to the XL. I personally didn't order the next size up because while I was kicking with them I could really feel that this fin was not stiff enough for training, and certainly not for kick sets. The rubber fin was bending too easily on every kick at the seam just beyond my toes on both fins - IMOP a serious design flaw for a "fitness fin." I could never do kick sets in these, but I could use these for snorkeling since the tips of the fins do spring back almost quickly enough to be responsive to my changes in direction and speed.SO COMFORTABLE BUT SO LONG. The black and yellow Cressi Palau Short Snorkeling Fins size LG--XLG had a great shaped boot, a strong and flexible heel strap, and they were absolutely the MOST comfortable boot of all those I tried, BUT these were definitely a better snorkeling fin and/or an open-water training fin. They were absolutely strong enough for open water training (which I rarely get to do anymore), but too way too long for endurance training in a pool with a harness. If these were 2 inches shorter they would have been my overall pick of a stiff training fin.I liked the way the SEAC Black Fins looked, but had to go up to the X-Large (11-12.5) and they were perfect. They have the fixed heal strap which I usually don't prefer, but this one is strong and stretchy enough to be very comfortable. The open heel did not make my feet feel unsupported at all. With barefeet they were a little soft, but with a 2mm or 5mm neoprene bootie they fit my feet perfectly. The front of the boot is comfortable lengthwise and widthwise, and there's no unnecessary gimmics in the fin design. As the ad says these are ideal for open water snorkeling for a good swimmer, and ideal for pool training. The fin is short enough and stiff enough for what I wanted to do. I can do flutter kicks or slow subtle kicks just to keep my feet afloat when I am working on my upper body. The fins do not add any extra buoyancy which I don't need with easy kicking or with a wetsuit on six months of the year. I am so glad I loved these.I just had to try something new with the TYR BP Burner Fins LG (size 11 -- Red & Black). They had to be exchanged for the XL - the Blue and Black, and I feared they might be too big, but I found they have a very stretchy and supportive heel pocket, that was as comfortable and supportive as the adjustable heel straps I usually prefer. The TYR EP Burners boot will be my spring and summer fins as they fit my naked foot or with a 2mm bootie perfectly. It's good that the fin is just that short because just another inch or so and the fin would be too flexible. Perfect design by TYR for a training fin. As the ad says "The perfect fins for training at race cadence." I kept these for warmer water training and the SEAC's for cold water training. I would use each of these for snorkeling, as I am a strong swimmer and I want my fins to be very responsive to the demand I am putting on them to change direction or to accelerate and change speed.I was not asked to give this review or compensated by anyone. Happy training.

This US Divers FIT Fin is the replacement for the Aqua Sphere Zip Fin. They fit feel and perform exactly as the now unavailable Zip. I swim laps in a pool, swimming 1300 meters in 35 minutes, which is a fairly fast speed. The fins perform very well for pool swimming.I needed to replace my Zip fins because they were stolen. After searching high and low I discovered they are no longer made by Aqua Sphere. Aqua Sphere replaced it with a Zip VX version which performs poorly compared to the original. This US Divers FIT Fin is the exactly replica for the ZIP. I wear a mens size 13 shoe. These do fit me tightly which is OK, tight just like the ones that were stolen. The straps on my old ones gave out completely. I replaced them on two occasions, but in 2015 Aqua Sphere did not have replacement straps for them. Because of the "tight" fit I used them for 18 months without straps, as I swam my foot went deeper into the pocket.I uploaded pictures of the new US Divers Swim FIT Fins, Old Zip Fin and New Zip VX fin for comparisons.

Size 13 is usually the cut off when it come to fin size. These did fit my larger foot but the back strap doesn't always stay on. Still, happy with fins overall. . . great leg workout

Perfect for what I was looking for Iaps in the pool I am a size 8 1/2 women’s and I was worried they would be too big they are adjustable to any size :)

The fins were a good fit. They performed well in pool water.

They were a replacement set of fins. I had a previous pair that I have over 7 years. that finally wore out and started to tare. Only thing I would do different to the fins is have a padded heel on the rear strap. I would wonderful for a fitness finning class I take at the YMCA in Waco, TX.

I was looking for a replacement for my Yellow Zips. The US Divers Fins are perfect. Same size and feel. I use them everyday in the pool. Great Fins!!

Great for in a small pool. Just what I need to do my leg exercises in the pool.
