10 Best Kids Swim Fins 2025 in the UK

The CAPAS Swim Training Fins are designed to enhance swimming performance and build leg strength, making them a solid choice for both beginners and professional swimmers. Made out of soft silicone, they offer a comfortable fit with a closed heel design to prevent hyperflexion, which is great for preventing unwanted foot movements.

The short blade design is particularly effective for promoting quicker, more powerful kicks, which in turn aids in improving speed and endurance in the water. This can be especially beneficial for young swimmers who are still developing their technique and stamina. One of the standout features is the unisex sizing that makes them versatile for both children and adults, as well as the lack of differentiation between left and right fins, simplifying the fitting process.

On the downside, some might find the lack of a more tailored fit (having identical fins for both feet) less than ideal for achieving maximum comfort and performance. Additionally, while they are great for training purposes, kids who are looking for fins with longer blades for more relaxed swimming might not find these to be the best match. These fins are highly rated by users, indicating a generally positive reception and reliability. The CAPAS Swim Training Fins are well-suited for kids interested in competitive swimming and training, offering a comfortable and effective tool for building swimming skills.

The MARU Training Fins in blue and lime are designed to aid young swimmers by boosting leg strength and foot flexibility. Made from high-quality silicone, these fins are comfortable and durable, making them a reliable choice for regular swimming sessions. The short fin design provides increased resistance and propulsion, potentially helping users to maintain a quicker swim pace and improve body positioning in the water. This can be particularly beneficial for kids looking to enhance their swimming skills and build endurance.

These fins fit sizes UK 3/5 (EU 36/38), which is a suitable range for many children but does limit its use for those outside this size bracket. The pull-on closure and regular fit type make them easy to wear, though some users might find it less secure than other closure types. Despite being primarily designed for adults, the features cater well to older kids or teenagers who are serious about swimming training.

A key strength is the silicone material, which provides a comfortable fit without causing irritations. However, the buoyancy might not be as pronounced as some swimmers prefer, given the short blade design, which focuses more on resistance and strength-building rather than speed. The striking blue and lime color combination is visually appealing, which could be a bonus for kids. These fins seem best suited for kids who have some swimming experience and are looking to improve their technique and endurance, rather than complete novices to swimming.

The CAPAS Snorkel Fins are a versatile and adjustable option, designed for a broad age range from kids to adults, making them ideal for family use. The adjustable open-heel design is a standout feature, allowing each fin to fit multiple sizes, which is perfect for sharing among family members or friends. The soft foot pockets and heel straps make these fins comfortable to wear, whether barefoot or with fin socks or dive booties. This flexibility helps prevent blisters and keeps feet warm in colder water.

The compact blade length makes the fins lightweight and easy to pack, ideal for travel and suitable for both pool and sea swimming. The use of Thermoplastic Elastomer (TPE) material ensures durability and flexibility. However, the shorter blade length might not provide as much propulsion as longer fins, which could be a drawback for more advanced swimmers or snorkelers looking for speed. Additionally, while the open-heel design adds versatility, it may not offer as secure a fit as closed-heel fins, especially for vigorous swimming.

The fins are well-reviewed, with a 4.4 out of 5-star rating from over 9,000 customers, indicating general satisfaction with the product. In summary, these fins are a good choice for casual swimmers, snorkelers, and families looking for a practical and travel-friendly option, though they may not meet the needs of those requiring maximum propulsion and a very secure fit.
