Description
Orca Training Fins: Build a Better Kick in the Pool and Open Water
Training fins are one of the most effective tools for developing kick technique and overall swim fitness. The Orca fins are short blade fins — the standard choice for structured swim training — which provide enough propulsion to reinforce correct kick mechanics without the oversize blade length that can mask poor ankle flexibility or put undue strain on the knees.
Regular use builds ankle flexibility, strengthens the key muscles used in kicking, and increases kick stamina. Swimmers who struggle with a flat or inefficient kick often see noticeable improvement in body position and stroke efficiency from consistent fins work, because the additional propulsion allows focus on technique rather than maintaining momentum.
Silicone Construction and Fit
The fins are made from 100% silicone — a material that combines comfort with durability and adapts well to different foot shapes. The silicone construction allows the fins to be adjusted to fit your feet, providing a more comfortable fit across a training session than rigid plastic alternatives. Silicone also holds up well to repeated chlorine exposure and the abrasion of poolside use.
High-Vis Visibility in Open Water
The high-vis orange colour has a practical purpose beyond aesthetics: it keeps you visible to training companions and other water users during open water sessions, even when submerged. For swimmers training in open water — particularly in busy or low-visibility conditions — this is a meaningful safety consideration.

What are short blade fins used for in swim training?
Short blade fins provide enough propulsion to maintain body position and allow technique-focused work, without the excessive kick power of long blade fins that can mask poor ankle flexibility or mechanics. They’re the standard choice for structured kick sets, drill work, and interval training in both pool and open water.
Why does the material matter for training fins?
Silicone fins conform more naturally to foot shape than rigid plastic, making them significantly more comfortable over a full training session. Silicone is also more resistant to chlorine degradation and poolside abrasion than cheaper materials, so the fins maintain their fit and feel for longer.
Are these suitable for open water training?
Yes — and the high-vis orange colour makes them a practical choice for open water sessions specifically, keeping you visible to training companions and other water users even when submerged. They’re useful for open water technique sessions as well as pool training.
Are these fins suitable for triathlon swim training?
Kick sets and drill work with fins are standard in triathlon swim training, particularly for athletes developing their swim from a non-swimming background. The short blade design is well-suited to the kind of technique-focused sessions that improve freestyle efficiency over time.
How do I choose the right size?
The fins are sized by EU and US shoe size. If you’re between sizes, sizing up is generally more comfortable than sizing down over a full training session.
