AK Footstrap Ether Set of 2

The AK Footstrap Ether is a lightweight, minimalist footstrap from AK Durable Supply Co., the accessories and hardware brand within the Airush family. Sold as a set of two with mounting hardware included, the Ether is built around a screw-adjust design that keeps the profile low and the weight down. It spans kitesurfing, wing foiling, and foil racing applications, offering a pared-back alternative to bulkier padded or velcro-closure straps.

AK Durable Supply Co. positions the Ether as a performance-first strap, prioritizing reduced mass over extra cushioning. The screw-based adjustment lets riders dial in their fit without adding bulk, and the soft strap material is intended to stay comfortable across longer sessions.

• Sold as: Set of 2 with hardware included
• Sizing: One Size Fits All (Medium–Large)
• Shoe size range: US 7–13
• Adjustment: Screw-adjust mechanism
• Recommended screws: M6 self-tapping, 22–28 mm long (length varies with board thickness)
• Intended disciplines: Kitesurfing, wing foiling, foil racing

The Ether suits intermediate to advanced riders who want a secure foot connection without unnecessary weight on the board. Its minimalist construction appeals to foil racers and freeriders focused on keeping their setup as light as possible, particularly on carbon foil boards where every gram matters.

With a US 7–13 fit range, the Ether covers most adult foot sizes in a single SKU. The screw-adjust system is straightforward to set and holds its position once locked down, making it a practical choice for riders who set their straps once and leave them. Riders who prefer on-the-fly adjustment or a wider size range may want to look at velcro-based options instead.

Within the AK Durable Supply Co. strap range, the Ether sits as the brand's streamlined, screw-adjust option. The ARC footstrap offers a more traditional velcro-closure design aimed at windsurfers and foilers who prefer tool-free adjustment. For riders who want one standard strap and one V-shaped strap on the same board, AK also sells the Ether V set, which pairs both styles with the same screw-adjust hardware.

At a retail price below $40 in this listing, the Ether set is competitively priced against comparable minimalist straps from brands like Duotone and Cabrinha, which typically fall in the $40–$60 range for a pair. It is a straightforward upgrade or replacement strap that fits standard M6 inserts found on most modern foil and kite boards.
