Open Heel Fins

Open heel fins are a type of swim fin or dive fin commonly used in scuba diving and snorkeling. Unlike full foot fins, which are worn like a shoe, open heel fins have an adjustable strap at the back, allowing them to be worn with neoprene booties or dive boots. This makes them suitable for colder water, rough terrain entries, or extended diving sessions.

Common Features

Adjustable Heel Strap

Allows a customizable fit and is usually made of rubber or silicone. It often features quick-release buckles for easy on/off.

Foot Pocket

Open at the heel and is designed to accommodate dive boots for comfort and thermal protection.

Blade Design

May be rigid, semi-rigid, or split depending on the type of propulsion desired. Some fins have channels, vents, or ribs to improve thrust and reduce drag.

Materials

Typically made from a combination of rubber, plastic, and/or composite materials for durability and flexibility.

Size and Power

Generally longer and stiffer than full foot fins, providing more power and efficiency, especially in strong currents or deep dives.

Heavy-Duty Use

Preferred for diving in colder waters or rugged conditions. It is often more durable and supportive for carrying scuba gear.
