How to Choose the Best Scuba Fins:
Paddle vs. Split & More
Scuba fins are a critical piece of gear that directly impact your efficiency, comfort, and control underwater. With various styles available, choosing the right pair depends on your diving style, experience level, and personal preferences. This guide will break down the key factors to consider when selecting scuba fins, comparing different types to help you make an informed decision.
Key Factors to Consider When Choosing Fins
1. Open Heel vs. Full Foot Fins
Open Heel Fins
Designed for use with dive boots, open-heel fins feature an adjustable strap and are commonly used for cold-water diving, shore entries, and drysuit diving. They provide a secure fit and extra protection for the feet.
Full Foot Fins
Full-foot fins slip on like a shoe and are designed primarily for snorkeling. While sometimes marketed for warm-water diving, they lack the protection, support, and versatility required for serious scuba diving.
- Not recommended for scuba diving: No foot protection, no insulation, poor fit adjustment
2. Fin Type: Paddle vs. Split

Traditional Paddle Fins
These fins have a longer, more flexible blade, providing a balance between thrust and ease of kicking. They are often preferred by recreational divers.
- Example: Mares Avanti Quattro – a flexible, powerful fin for various conditions

Technical Paddle Fins
Shorter, stiffer paddle fins are designed for maximum control and precision, making them ideal for technical diving.
- Examples: OMS Slipstream – stiff and neutrally buoyant, Deep6 Eddy’s – lightweight but powerful

Split Fins
Split fins have a divided blade that allows water to pass through, reducing resistance. However, they lack power in strong currents and are not ideal for precise maneuvering.
- Best for: Divers who use only flutter kicks, long-distance swimming in calm water, anyone with leg or knee problems
- Not recommended for: Technical diving, strong currents, frog kicks
3. Additional Considerations
- Stiffness & Material: Soft fins are easier to kick but less powerful; stiff fins provide better control.
- Buoyancy: Negatively buoyant fins may help with trim; positively buoyant fins will float.
- Straps: Spring straps are durable and easy to use; traditional straps require periodic tightening.
Final Thoughts
The best scuba fins depend on your diving environment, comfort, and kicking style. Paddle fins offer power and control, while split fins provide effortless kicking but come with trade-offs. Full-foot fins should be avoided for scuba diving.
