4.5 stars, In an industry saturated with fins, meaningful innovation is hard to achieve. With the new Slip Fin, FINIS has not only done that, but may help shape the future of propulsive training in aquatics.

I’m obsessed with the SlipFins. I call them my “Happy Feet” because they’ve made me rediscover the joy of swimming again. I love how they feel like extensions of my own feet, allowing me to use my legs in a more natural way than traditional fins. They’re super comfortable and provide just the right amount of lift and propulsion. I get a great lower body workout without changing my stroke, body rotation, or cadence. Oh, and the extra speed makes me feel like a real swimmer

The technology from the slip fin pro is like no other set of fins. It mimics exactly how you should kick in the water, and really focuses on movement in both directions, it’s the first set of fins created which are completely strapless, and are perfect for any level of swimmer in the water!

We are excited for the release of the newest revolutionary product from Finis, with their new SlipFin. Having seen the prototype, this fins will be more durable, comfortable, and enhance training for athletes at all levels.

Honestly these fins are awesome. I was really surprised by how well they stay on and how they feel in the water. I'm wearing a size M and have what I'd say is a pretty average width foot, I wear a men's 9.5 shoe. The first time I used them I didn't get all the water out so they felt a little loose. Then I figured out if I fold down the tip of the fin to get the water out they stick on really well and aren't going anywhere. Super lightweight, super comfortable and just really fun to swim with. Can't recommend them enough.

Comfortable, lightweight, flexible and fast! FINIS did it again 💛🥇 incredible feelling of the water in both the up and down kick. Travel friendly is plus 🧳, you can just squeeze them in your backpack and wont take any space so you can carry them everywhere! 5 stars ⭐️⭐️⭐️⭐️⭐️

If you're on the fence about trying the FINIS SlipFin Pro, just do it.
The Fit: I measure exactly 25 CM for my instep circumference and went with the Size Medium. They fit my feet like a glove. No rubbing, no blisters, just pure comfort.
Weight & Travel: They are super lightweight and packable, making them incredibly easy to throw into a swim bag or take on a trip without weighing you down.
In the Water: Kicking feels extremely natural. Unlike bulky traditional fins, these allow you to actually feel the water, making it easy to focus on your body line and maintaining the right tempo. They are versatile enough to handle grueling, long endurance sets just as easily as high-intensity speed sets.

The Verdict: The best thing about them is that they just work. After a couple swims, they become completely intuitive and honestly just make swimming a lot more fun. Trying to go back to traditional fins now feels like a massive step backward. Highly recommend

Love mine! The strapless design feels like a true extension of my foot. The crazy thing is I didn’t “feel” like I was going faster until I touched the wall and looked at the clock. Unlike traditional fins, I can train at race-like speeds while maintaining the same technique and kick-to-arm ratio I use in competition. Total game changer.

I was hooked after 15 seconds of wearing the Slipfin. I get asked time after time again to try products, endorse gear, see what's new, etc. These are unlike anything I've ever used. After using them, I immediately went to my phone and shot a testimonial video and sent it to John Mix. I was blown away. The form fit, the comfort, the fact that the entire ankle area is wide open and free to move (think no blisters for little kids) and no rigidity issues like certain fins have. I tried my hardest to shake the fins off my feet -- and I could not. But they are so easy to slip on and then remove once you learn that all it takes is a finger to break the form fitting seal that keeps the fin comfortably yet snugly in place. I'm a huge fan of the Slipfin - and I'm willingly telling others about it. Well done Finis! You have a hit on your hands! Mike Koleber, Nitro Swimming @Coachmikenitro

As a distance freestyler I use my feet to drive my hips and leave the propulsion to my upper body and my rotation. When I train with heavier fins requiring more energy and kick rate I experience a disruption in my technique and focus. They put my brain into my feet instead of leaving it in my head where it belongs.

Using SlipFin was a return to a profoundly natural feel after 25 years of the arms race in training fin technology. Because it feels so natural and is so much more manageable than anything else I’ve ever used I put them on every chance I get - I’ve even used them for a full practice.

If you want a fin that connects your toes to your fingertips I can’t recommend it enough!

I have never enjoyed fins before trying on these slip fins. The opening of the fin fits nicely around the instep of my foot (not the back of the foot) which allows for a very comfortable fit and nothing rubbing on my heel. The material it's made of is slippery and soft. Just slip it on, squeeze out the air/water and kick away. I also used to get foot cramps and blisters from wearing fins BUT I was pleasantly surprised I did not get blisters, didn't have to wear socks to protect my feet AND no cramps!! These are also lightweight, so travel will be easy!!! I am so glad I bought them.

Honestly this product is something special, I’ve never experienced anything like it. The way it feels, and the speed I can generate is extraordinary.

We tried the SlipFin Pro on approximately 15 swimmers; half masters, half club high school-aged athletes. Most really liked the SlipFin once they were in the correct size. I believe the SlipFins will be used as kick developers. Very innovative and fun!

Perfect fins. Easy to use, light on the feet
Top fins. The best.

My foot measures 26CM so I am a size Medium. I love the Slipfins, they were a little hard to put on the first few times and I was not getting my foot in deep enough. Within a few times I have perfected how to put them on and I love the comfort and performance. I also ordered the size large, they are easier to put on, my foot does not go as deep into the pocket, but for easy freestyle and longer swims I will use the large. So I would say the fit is pretty universal.

I am new to swimming and swam my first 1k straight yesterday with the slipsfins on. It makes getting into swimming SO much more fun and less frustrating! I can fully focus on my technique while enjoying a natural feel of propulsion. They truly make a beginner feel like they belong into water! I love them!

The past month, I have a couple of swim camps with over 100 swimmers, plus sharing with some of my swim coaching friends. The comments started out by they feel weird, then these fins feel awesome. They are light and my feet have more flow with the SLIPFIN. I can't believe they work with the breaststroke kick and going fast in and out the wall. It is a great product, no more sores on my feet!
