Ozone Board Leash Straight Ankle

The Ozone Board Leash Straight Ankle is a straight-cord board leash built for kitesurfing, wing foiling, surfing, and stand-up paddleboarding. Produced by Ozone — a brand well established in the kite and wing foil market — this leash uses a traditional straight-cord layout rather than a coiled design. The straight configuration is a familiar choice for surf and wave-kite riders who prefer a low-profile cord that lies flat in the water and provides a direct, predictable connection to the board.

Ozone builds the leash around a TPU (thermoplastic polyurethane) cord paired with dual stainless steel swivels to resist tangling during sessions. The ankle cuff is reinforced with Hypalon — a durable synthetic rubber commonly used in inflatable boat construction — and lined with soft neoprene for comfort against bare skin. A webbing rail saver distributes load across the board's tail to protect the rail, and a small key pocket is stitched into the cuff for convenience.

This leash suits wing foilers, kitesurfers, surfers, and SUP riders who prefer a straight cord over a coiled alternative. Straight leashes generally sit behind the rider in the water with less recoil tension than coiled versions, which some riders find less distracting — particularly in surf or wave-riding scenarios where a snapping coil can interfere with foot movement on the deck.

Riders who already use a waist leash for their wing and want a separate board-to-ankle connection will find this a straightforward option. It is equally appropriate for beginners who need a reliable tether to their board during water starts and for experienced riders in wave or downwind conditions. Riders who prefer the cord to stay out of the way of their feet during kneeling starts may want to consider Ozone's coiled calf-cuff variant instead, as that configuration reduces the chance of the line wrapping around the ankles.

Ozone offers its board leash range in both straight and coiled cord styles, each available with either an ankle cuff or a calf cuff. The coiled versions come in 8-foot and 10-foot lengths with an 8 mm cord diameter. This straight ankle model sits alongside those options as the more traditional choice in the lineup. Ozone also sells a dedicated Wing Leash System — a separate product that connects the rider to the wing itself — so the Board Leash is specifically the board-side tether in a two-leash setup.

At its price point, the Ozone Board Leash Straight Ankle competes with surf-origin leashes from brands like FCS and Dakine, though it is marketed specifically with wing foiling and kitesurfing use cases in mind. Riders already invested in other Ozone accessories may appreciate keeping their safety gear within one brand ecosystem.
