The fin is designed for the perfect execution of the tempo, therefore it increases the stretching of the ankle in the sole direction. For beginners, this can cause leg or foot cramps. In such a case, take off your fins, carefully stretch your feet and toes into a ticking position with your hands, then shake them off and swim 100-200 meters without fins in breaststroke, or perhaps do a few angles at the bottom of the pool while diving under the water. Gradually get your feet used to the fin, take it off every 400 meters and include relaxing swims without fins.

The fin can break the leg. This can be completely eliminated by using neoprene socks or traditional secret socks. Professional athletes do not use this, because there the time result is the primary consideration. The direct connection between the fin and the leg is important. Violinists don't play with gloves either, of course. That's why professionals tape their broken feet with Leukoplast before going into the water, so it stays on even during a 2-3 hour training session and protects their feet from further breaking. During everyday use, the foot and the fin adapt to each other and become extremely comfortable. It doesn't break, it doesn't press. After a longer absence of several weeks, the habituation must be started all over again.

No problem!! :) Since it is made entirely of rubber -unlike its non-repairable silicone counterparts available in the store-, it is easy and quick to repair, even if you have a flat tire. Do-it-yourselfers can easily repair it at home with patches cut from the inner tire of a car or bicycle. Of course, our company will carry out the professional repair if you send back the damaged product. We use top-quality SC 2000 glue for the repair. You can have the repair done at any helpful tire repair shop. Professional repair does not affect the fin's performance or use value. With daily use, its lifespan can be extended up to decades.

Of course it flows in because it has a hole :) This is a great sports tool because of its simplicity. It was designed so that air can flow through it as easily as possible. That's why it doesn't have a chute or valve, because that reduces sports performance to a great extent. It is an extremely easy-to-use tool once you have mastered the special breathing technique. When the tube fills with water, place your tongue against the end and blow the water out through the tube with a forceful spit-blowing motion. We can also organize a distance gargoyle competition. The kids really enjoy it. Using the device greatly improves the functioning of the respiratory muscles. A professional scuba diver who competes with a large female dolphin blows out the water with each breath, as water enters the tube at every pace during the dolphin's movement. Of course, you don't need to pay special attention to this when using it at the skill level - everything goes by itself. Even 6-year-old children learn how to use it in a matter of weeks.

Taking air underwater is unusual for the first time, because we are not fish. Therefore, when our face is in the water, it happens that initially someone wants to take air through their nose and mouth at the same time. Air is taken in through the mouth, through the pipe. If someone also wants to take air through the nose, the result will be nasal washing. So, inhaling air through the mouth, exhaling through the nose and mouth at the same time. You can use a nose clip or a speed diving mask that includes the nose, so the problem is solved in one fell swoop. However, it is worth learning the correct breathing technique with an open nose, because in terms of sports performance, breathing is more effective if you can blow out the air through your nose, even if you stretch it for a long time, over several paces.
