Arena Unisex Training Swim Fins - Lightweight Short Blade

In this review the Arena Unisex Adult Training Fins are assessed as a practical, comfortable option for swimmers focused on technique and conditioning. The single biggest reason to buy is their short blade design combined with soft silicone construction, which makes them effective for improving kick frequency and push off after turns while remaining comfortable for long training sessions. The review looks at fit, material, and training benefits to help swimmers decide if these fins suit their workouts.

Key Features

• Short blade: Promotes a higher kick frequency and more efficient forward motion during drills, which helps refine leg technique.
• Soft silicone construction: Delivers outstanding comfort against the foot and reduces the chance of blisters during repeated sets.
• Open-heel design: Provides freedom of movement and an adjustable fit that is easy to slip on and off between sets.
• PVC free material: Uses thermoplastic elastomer that is durable and avoids PVC, appealing to swimmers preferring softer, long-lasting materials.
• Training focus: Built for fitness and competitive swimmers for power and technical work rather than long-distance propulsion.

Who It's For

These fins are best for fitness swimmers, club athletes, and triathletes who want to work on ankle flexibility, leg turnover, and turn push-offs. The short blade encourages technique work and higher cadence kicks that translate well into regular swim sets and technical drills.

Swimmers seeking maximum propulsion for surf or long open-water sprints, or those needing a very rigid blade for snorkel-style long-distance kicks, should look elsewhere; this model emphasizes comfort and technique over raw thrust.

Pros & Cons

Pros

• Comfortable, soft silicone reduces blister risk during long practices.
• Short blade design improves kick frequency and technical leg work.
• Open-heel construction allows flexible fit and easy on/off between sets.
• PVC free thermoplastic elastomer is durable and feels high quality.

Cons

• Sizing has mixed feedback, so trying them on or checking size guidance is advisable.
• Not ideal if you need maximum propulsion for long-distance open-water kicking.
