Training fins Speedo BIOFUSE/TRAINING FIN AU – short blade swimming fins for technique and conditioning

Speedo BIOFUSE/TRAINING FIN AU are short-blade swimming fins developed for training environments to support improvement of kick technique, ankle flexibility and leg conditioning. Designed by Speedo for pool practice, these fins balance propulsion and natural foot movement to help swimmers focus on stroke timing, power application and propulsion awareness during coached sessions or individual workouts.

Advantages

These short-blade training fins provide controlled propulsion without overly altering natural kick mechanics, allowing swimmers to feel the water and refine ankle motion. Constructed for repeated pool use, the design supports interval training and drill sets while reducing excess drag compared to long fins. The fins' profile encourages a shorter, faster kick and helps build lower-leg strength and endurance with consistent training.

Suitable for

• Swimmers working on kick technique and ankle flexibility
• Coached drill sessions focused on stroke timing
• Interval and conditioning sets in the pool
• Swimmers aiming to increase propulsion awareness without altering stroke rhythm
• Swim coaches and instructors using tools for technical development

Key specifications

• Short blade length for reduced drag and natural kick mechanics
• Training-focused construction suitable for frequent pool use
• Ergonomic foot pocket for secure fit and improved comfort
• Material blend designed to balance flexibility and propulsion
• Compact profile compatible with drill and lap work

How to use

Place the fins on dry feet and ensure the foot pocket fits snugly but comfortably to avoid chafing. Use the fins during warm-ups, technical drill sets, and interval training to reinforce a shorter, faster kick and to develop ankle range of motion. During coached sessions, combine fin work with kickboards or bodyposition drills as instructed to isolate leg action or integrate with full-stroke practice. Rinse the fins with fresh water after each session and allow them to dry away from direct sunlight.

Usage recommendations

Begin with short intervals when introducing short-blade fins to your routine, progressively increasing duration as ankle flexibility and leg strength adapt; consult a coach to integrate fins into stroke-specific drills without compromising technique.
