Smooth fins for better streamlining!

Wish fins smoothed your stroke?

shinfinTM fins streamline your whole body as they propel you forward. Throughout your kick, the fin thrust direction actively encourages proper body streamlining. So these smooth fins raise and straighten your knees, level your thighs, and raise and straighten your hips.

So how do they smooth your kick and hence streamline your whole body? The water flow over the fins raises and straightens your knees. This in turn lifts your thighs more horizontal. That raises and straightens your hips, so the fins push you forward with more horizontal, streamlined legs. Finally, all the above guides your upper body into a more horizontal and streamlined position.

Most importantly, your streamlined body position minimises drag. It also encourages a smooth kick thrust from your hips, giving fast fin propulsion. This is how good swimmers swim.

So these smooth fins propel you fast. Furthermore, they also teach and strengthen you for natural smooth strokes for freestyle, backstroke and butterfly.

Different to foot flippers

They feel much more natural and smoother compared with regular flippers. Swimmers and coaches know that regular foot flippers cause too much knee bend and too much hip bend, sloping your thighs down in the water. So they call it a “bicycle kick”. It is poorly streamlined, inefficient and feels uncomfortable.

Worse, your body remembers this poor “bicycle kick” even after you take the foot flippers off. So foot flippers cause bad habits which stay with you. How do they ruin your efficient, streamlined kick? What bad habits have they given you?

To work smoothly, fins need to be on your legs, not on your feet. Would you like fast fins that streamline your legs and body? Maybe you would like more efficient fins that improve your whole stroke efficiency including legs, body, arms and breathing. Perhaps you just want smoother propulsion from your fins so you can enjoy more natural smooth swimming.

Higher straighter knees

shinfinTM fins connect directly to your lower legs. So the water flow over the fins gently pushes your lower legs upwards. This raises your knees and straightens your knee joints. It also reduces knee drag through the water. So the fins propel you forwards more efficiently, like good swimmers kick.

These fins lift your knees even at slow swimming speeds. So they lift your knees even if you don’t kick and just swim with your arms. To fix severe knee drop, fit the fins higher to lift your knees even more. shinfinTM fins give higher straighter knees for a better kick with a more horizontal kick propulsion.

In contrast, regular foot flippers make you bend your knees too much, dropping your knees well below the horizontal.

Horizontal thighs

Higher straighter knees lifts your thighs more horizontal. So the smooth fins propel you forwards more horizontally, pushing straight along the line of your thighs. Horizontal thighs also reduces the wasted energy from your thighs dragging through the water. So shinfinTM fins give you horizontal thighs for a more efficient smooth kick. In other words, you get faster fin propulsion with less drag.

In contrast, foot flippers slope your thighs down well below the horizontal, creating unwanted drag and wasting energy.

Higher straighter hips

Horizontal thighs lifts your hips higher and encourages straighter hip joints. So shinfinTM fins stop your hips sinking and bending too much. This is a common problem that hinders many swimmers. These fins give higher straighter hips to improve your kick from your hips. You feel so much better moving through the water.

In contrast, foot flippers make you bend your hips too much, dropping your hips down in the water.

Horizontal torso

Higher straighter hips keeps your torso more horizontal. A horizontal torso reduces the frontal drag of your chest moving through the water. So this optimises the speed you get from your kicks. It also makes best use of the power of your arm pulls.

In contrast, foot flippers slope your torso down, causing more chest drag.

Faster streamlined body

Full body streamlining is a sequence of all the above. Higher straighter knees gives horizontal thighs. Horizontal thighs gives higher straighter hips. Higher straighter hips gives a horizontal torso. Through their design, shinfinTM fins actively encourage this full body streamlining whilst they are delivering power to propel you forwards.

Your knees and hips are higher and straighter. Your legs and torso are more horizontal. Throughout your stroke, shinfinTM fins streamline your whole body to swim faster.

In contrast, foot flippers don’t give the same body streamlining sequence. Instead, they create extra drag.

Efficient smooth thrust

shinfinTM fins do much more than streamlining your body. They propel you with smooth forces throughout your kick. You feel this smooth thrust working continuously during your down kicks, up kicks and transitions in between.

Because the fins connect directly to your shins, the thrust force goes along your shins, through your knees, directly along your thighs and horizontally through your hips to your torso. So it propels your body forwards efficiently, with power originating from your hip movement.

This is how good swimmers kick. But even if you don’t know how to kick properly, the natural flex of these smooth fins will guide you into the correct kick. Thus shinfinTM fins deliver smooth thrust throughout your kick.

In contrast, foot flippers make you kick from your knees. Hence they encourage the common, inefficient “bicycle kick” problem with poor streamlining.

Smooth fins improve freestyle, backstroke & butterfly

The end result is that shinfinTM fins help you improve your stroke for freestyle, backstroke and butterfly.

In contrast, foot flippers slow your kick, lower your body and degrade your freestyle, backstroke and butterfly. If you care about your swimming strokes, why would you use them at all?
