Armstrong Waist & Ankle Board Leash

The Armstrong Waist & Ankle Board Leash is a coil-style board leash from Armstrong Foils designed primarily for wing foiling, though it also suits SUP racing, downwind paddling, and prone foil surfing. Sold under the product code WCBL, this leash uses a waist-mount attachment point paired with a coiled cord to keep the line off the deck and out of the water. The package includes an interchangeable ankle strap, giving riders the option to switch between waist and ankle attachment depending on the session or discipline.

The waist belt is adjustable to fit a range of body sizes and fastens with what Armstrong calls a bomber clip — a secure closure that is still quick to connect and release between runs. The coiled cord stores compactly when not under tension and stretches as needed during a fall, reducing the chance of the leash wrapping around the foil mast or tangling underfoot.

• Attachment options: Waist belt (primary) and ankle strap (included)
• Cord type: Coil
• Closure: Adjustable waist belt with quick-connect clip
• Product code: WCBL
• Price: $74.99 USD

This leash targets wing foilers of any skill level who want their arms completely free to handle the wing. A waist-mounted board leash eliminates the need to reposition a traditional ankle leash after every crash, which is a frequent annoyance during learning and progression sessions. Because the coil rides above the waterline when on foil, it adds virtually no drag — a practical benefit for intermediate and advanced riders focused on speed or distance in downwind runs.

The included ankle strap broadens the leash's usefulness beyond wing foiling. Riders who also SUP surf, prone foil, or paddle flatwater can swap to a conventional ankle setup without buying a second leash. This dual-attachment approach makes it a practical choice for multi-discipline riders who want one leash that covers several use cases.

Within Armstrong's own accessory range, the Waist & Ankle Board Leash sits in the middle of a six-leash collection. Below it are the Floating Coil Ankle Leash and Floating Coil Calf Leash, both priced at $49.99 and available in two diameter and length options. Above it is the Downwind Waist Board Leash at $79.99, which comes in sized waist bands (S/M and L/XL), and the Ultimate Waist Leash at $99.99, Armstrong's top-tier option with sized fit and additional features. The Waist & Ankle Board Leash occupies a middle ground: it offers the waist-mount convenience of the pricier models while bundling an ankle strap for versatility, all at a lower price point than the sized alternatives.

For buyers comparing across brands, coil waist leashes from Dakine, Ocean Rodeo, and Duotone occupy a similar price bracket and serve the same wing-foil and SUP audience. The Armstrong leash distinguishes itself mainly through the included ankle strap, which most competitors sell separately.
