Finis SlipFin Pro swim fins deep pink

The Finis SlipFin Pro is a strapless swim fin that gives you the propulsion of a fin with a lighter, more natural feel. This short, compact swim fin slips over the front of your foot and leaves your ankle and heel completely free, so you keep moving smoothly and hold your technique clean. Ideal for swimmers who want to train faster and at race-pace rhythm without the bulk and weight of traditional swim fins.

Whether you want to refine your stroke or simply move a little quicker through the water, the SlipFin Pro lets you feel how a good push-off should feel.

Finis SlipFin Pro at a glance

• Strapless design: a soft, flexible seal keeps the fin in place without straps or a heel cup, so there is no rubbing at your heels.
• Open heel: your heels and ankles stay free for more freedom of movement and a natural kick.
• Light propulsion: the power of a swim fin without the weight and bulk of a classic flipper.
• Natural kick feel: the fin moves with your body and supports your rhythm and balance, so your technique stays clean.
• Floats in the water: the fins stay at the surface, so you spot them quickly in the pool or open water.
• Quick on and off: with the simple dip, slip and squeeze method the fin sits right in just a few seconds.

Strapless design that stays in place

The heart of the SlipFin Pro is its patented, strapless design. The fin slips over the front half of your foot, where a soft seal creates a gentle suction that holds it in place. No straps, no heel cup and therefore no pressure points or rubbing on your heels. You put the fins on in a few seconds: dip them together with your feet in the water, slip them on and squeeze the top to push out the excess water for a comfortable fit.

Light propulsion for better technique

Traditional swim fins often feel heavy and bulky. The SlipFin Pro instead gives you the propulsion of a fin with a light, natural feel that supports your stroke and your race-pace rhythm. Because the fin moves with your kick instead of taking it over, your technique stays clean and you feel more clearly how a good push-off from your hip should run. That makes these swim fins pleasant for technique sets, tempo work and easy laps in which you work on your stroke.

Who is the Finis SlipFin Pro for?

The SlipFin Pro suits a broad group of swimmers, from beginner to competitive swimmer. Fitness swimmers who find classic swim fins too bulky or uncomfortable discover a lighter alternative with this fin. For triathletes and open water swimmers it helps that the fins keep floating and are therefore easy to see, while the compact size takes up little room in your swim bag.

Good to know

The SlipFin Pro is a compact training fin built around technique and a natural kick feel, not a long diving or snorkelling fin for maximum propulsion. If you mainly want to go as fast as possible, a long fin gives more power. You choose your size based on the circumference of your instep; if you are between two sizes, your preference for a snug or a roomier fit decides. Rinse the fins after use and let them air dry, out of direct sunlight.

Frequently asked questions about the Finis SlipFin Pro

How does the SlipFin Pro stay in place without straps?

The fin has a patented, strapless design with a soft seal around the front of your foot. That seal creates a gentle suction that holds the fin in place, without straps or a heel cup. To put them on, you dip the fins in the water, slip them on and squeeze the top to push out the excess water. This way the fin sits securely and comfortably, even during a powerful push-off.

Which SlipFin Pro size do I need?

The SlipFin Pro comes in sizes S, M and L, which you choose based on the circumference of your instep. Use a tape measure, or a shoelace that you then hold against a ruler, to measure the circumference of the top of your foot just in front of your ankle and compare it with the size chart. If you want a snug, sporty fit, choose the smaller size; if you prefer a little more room, go one size up. If you fall between two sizes, let your preference decide.

Who is the SlipFin Pro suitable for?

The SlipFin Pro is suitable for swimmers from beginner to advanced level who want to work on their technique and speed. Fitness swimmers appreciate the light, comfortable feel, while competitive swimmers use the fin for technique sets and tempo work. Swimmers who found swim fins uncomfortable until now often get on well with this strapless design too.

Are these swim fins suitable for triathlon and open water?

Yes, the SlipFin Pro is pleasant for training in open water and triathlon. The fins keep floating at the surface, so you find them quickly, and the compact, light size takes up little room in your bag. The natural kick feel helps you keep your stroke clean outside the pool too. For pure propulsion over long distances, a longer fin stays more powerful.

What is the difference from traditional swim fins?

Where classic swim fins are often heavy and closed with a heel strap or heel cup, the SlipFin Pro is strapless and open at the heel. That makes it feel lighter, lets your ankle move more freely and means you have no rubbing at your heels. The propulsion is deliberately a little more subtle, so your technique stays central and the fin does not take over the work.

How do I care for the SlipFin Pro?

Rinse the fins after every session with cool, non-chlorinated water and let them air dry. Store them preferably separately and without compressing the foot section, so they keep their shape. Do not leave the fins in direct sunlight or in high temperatures, because that can deform the material. This keeps the fit and the performance in good order.
