CAPAS Swim Training Fins Short Blade - Build Speed & Leg Strength

In this review of the CAPAS Swim Training Fins, the bottom line is clear: these short blade fins are made for swimmers who want to build leg strength and improve sprint speed without bulky equipment. They suit lap swimmers doing long freestyle sets, kick sets, and backstroke practice who value a comfortable fit and a training tool that promotes quicker, more compact kicks. The most compelling reason to buy is how the short blade design encourages faster turnover and stronger ankle flexibility while feeling soft and secure on the foot.

Key Features

• Short blade design: promotes shorter, faster kicks that generate effective propulsion for sprint and endurance training.
• Comfortable foot pocket: soft rubber foot pocket provides a secure fit and reduces foot discomfort during long sets.
• Closed heel construction: inhibits hyperflexion at the ankle for safer, more controlled kicking mechanics.
• All skill levels: suited for fitness swimmers and competitive athletes alike for freestyle, backstroke, and prolonged kick sets.
• Ambidextrous pair: both fins are identical so there is no left or right difference, simplifying use and storage.

Who It's For

These fins are best for swimmers focused on technique and conditioning: triathletes, masters swimmers, and club athletes who run long kick sets or want to develop ankle flexibility and leg power. The short blade favors faster cadence and a training feel close to regular swimming while still adding measurable propulsion.

Less suitable are open-water swimmers who prefer long-blade speed fins for glide, or beginners who need very soft, corrective fins; also anyone who requires a precisely asymmetrical left/right fit should look elsewhere since the pair is identical.
