## Long description

Master Syreni Ogon monofin for children (size 28–36) is a single-blade swim fin designed for mermaid-style swimming, swim training and recreational use in pools. The monofin combines a streamlined blade with a comfortable foot pocket to produce stronger propulsion than individual fins, supporting development of leg and core muscles and helping the swimmer maintain an efficient body position in the water. Intended for use by children who fit the indicated size range; correct fit and supervision are recommended before each use.
Advantages
The single-blade configuration increases forward thrust and promotes an undulating kick that mirrors mermaid-style movement while strengthening lower body and core muscles. A soft foot pocket and ergonomic shape reduce pressure points on the feet and help keep the blade aligned with the swimmer’s legs. The design is suitable for pool environments and for structured training sessions or recreational mermaiding, enabling gradual skill development and improved body alignment in the water.
Suitable for
Children learning mermaid-style swimming
Swim lessons focused on propulsion and body position
Recreational pool use and playful aquatic exercise
Developing leg and core strength in young swimmers
Key specifications
Size range: 28–36 (children)
Configuration: single-blade monofin
Foot pocket: soft, ergonomic for barefoot use or with thin socks
Recommended environment: swimming pools and supervised aquatic areas
Primary benefits: increased propulsion, improved body position, muscle development
How to use
Before each use, check that the monofin fits the child’s feet comfortably without slipping and that the heel and toes are correctly positioned in the foot pocket. Enter the water under supervision and start with short, low-intensity sessions to become accustomed to the single-blade motion. Use gentle undulating kicks originating from the hips rather than isolated knee movements. Combine practice with regular swimming drills and safety breaks. Remove the monofin if the child feels discomfort, fatigue, or has difficulty controlling direction.
Usage recommendations
Verify fit before use and always supervise children while using the monofin. Limit initial sessions to short practice periods, teach proper undulating technique, and avoid deep or unsupervised waters until the child demonstrates confident control.
