Foot Sling Basic Knowledge and Introduction

The purpose of fins:
1. Help students with swimming exercises (help improve the swimming skills of freestyle, backstroke, and butterfly, and help learn wave-like movements, etc.)
2. Enjoy the fun of swimming

Foot Sling Classification:
1. Short fins, with fin lengths ranging from 1-2 inches, are ideal for freestyle and backstroke kicking, as they allow for normal kicking frequency. Of course, you can also use them for breaststroke and butterfly, or when learning wave breaststroke - they are suitable for all four strokes.
2. Long fins (the same length as the feet). Suitable only for butterfly swimming and learning wave swimming (crawl, butterfly)

How to use fins?
Flippers extend the length of your feet and legs, making your stroke more effective and faster. In fact, using flippers in sprint training helps to keep your body in a more fluid state. Additionally, you will reap many benefits, experiencing a good feeling of water. However: Some swimmers are not aware that they bend their knees too much, in fact, they use bent knees to replace hip power for their stroke.

Problems that may occur when using fins, and how to overcome them?
When you decide to start swimming with fins, go slow at first, giving your muscle groups time to adapt. Some swimmers have experienced cramps in their calves, but following the following method (intermittent practice with alternating fins and without, 25 meters with fins for butterfly leg practice, followed by 25 meters without, after four months, the ankles will become more flexible and won't cramp). Long fins are suitable for diving in the sea (essential for Hainan Island, the Maldives), while short fins are suitable for use in pools, rivers—a must-have for players. Long fins are used for practicing butterfly and waveback, as they are too long for fast leg strokes, so they are not suitable for practicing freestyle and backstroke. Short fins, on the other hand, can be used for all four strokes.

Function: This is a training fin for scuba swimming, which can train leg strength and abdominal strength. It has a adjustable and streamlined anti-skid design. It is durable and less prone to damage, and it feels extremely comfortable to wear. It is patented.

Useful Tips for Using Fin Socks

（1）When performing the leg action, it is essential to use the thigh to drive the calf, maintaining a gentle yet firm strength, with a whip-like motion. It is crucial to avoid using only the calf without moving the thigh, which can cause the fins to hit the water surface, creating a large splash without effect. The leg action should be directed under the water surface, with a slight bubble of foam rising.

(2) Choose fins of the appropriate length, size, and firmness for the athlete based on their age, training level, lower limb strength, and kick technique characteristics, not necessarily the larger, longer, or softer the better.

When practicing with double fins, the angle of the feet inwards should not be too large, otherwise the fins will hit each other, affecting the leg kick effect.

The wide area of fins can provide you with powerful propulsion, allowing you to generate power without having to use your hands, which frees up your hands to perform other tasks. Fins are mainly divided into two types: those with no heels and those that fit over the feet. Fins with a sock-like design are usually used in warm water or for snorkeling. Fins with no heels are designed to be used with diving boots. Large and hard fins are fast to use but can lead to fatigue and cramps; smaller and softer fins lack the power to push.

Fins come in different materials, designs, and features. The design of fins includes: the keel, which adds rigidity and balance to the fins; drainage holes, which reduce resistance to increase efficiency; and flow channels, which allow water to smoothly slide over the fins, increasing speed. Choosing fins should be based on your body type, stamina, and diving environment; comfort and suitability are key.
