The ECCO Biom G5 BOA combines high-performance athletic functionality with a progressive, modern design. Built on the updated BIOM® last for a natural, supportive fit, this shoe features GORE-TEX waterproof technology, ECCO Performance leather construction, and the BOA® Fit System for precise, micro-adjustable closure. Whether you're walking 18 holes in dry conditions or wet morning rounds, the Biom G5 BOA delivers the traction, stability, and all-day comfort that serious golfers demand.
Rooted in ECCO's biomechanics research, the updated BIOM® last is engineered to mirror the natural shape and movement of the human foot. The last ensures even weight distribution, reducing strain on joints and allowing a more fluid, natural stride throughout all 18 holes. At the same time, the design provides the lateral support and stability essential for the rotational forces of the golf swing, so you never have to sacrifice performance for comfort. The result is a shoe that truly works with your body rather than against it.
The integrated GORE-TEX membrane delivers a guaranteed 100% waterproof barrier against rain, dew, and wet grass, ensuring your feet stay completely dry from the first tee to the final putt. Critically, the GORE-TEX technology is also highly breathable, allowing excess heat and moisture vapour to escape so your feet remain comfortable and blister-free even during warm rounds. This combination of waterproofing and breathability represents the gold standard in golf footwear weather protection, and ECCO's construction seamlessly integrates the membrane without compromising the shoe's sleek profile.
The FTS 3.0 (Fast Twist 3.0) outsole platform accepts Pivix spikes, which are combined with additional notched hybrid sections in the outsole to generate exceptional traction and directional stability. The spike placement is strategically mapped to the areas of peak pressure during the golf swing, anchoring your stance through impact for consistent, powerful strikes. The hybrid traction zones between the spike positions also provide a smooth, secure feel when walking on paths, bridges, and other hard surfaces around the course. Whether the fairway is firm and dry or soft and wet, the FTS 3.0 system keeps you planted and in control.
ECCO's proprietary FLUIDFORM™ technology creates the midsole and outsole as a single, unified structure rather than bonding separate components together. This direct injection process produces a midsole with a precisely tuned density that provides responsive cushioning underfoot without unwanted bulk or weight. The technology delivers an optimal balance between impact absorption and energy return, meaning your feet feel supported and springy even during the latter holes of a long round. FLUIDFORM™ also contributes to the shoe's notably lightweight feel, reducing fatigue and helping you maintain focus and posture throughout your game.
The BOA® Fit System replaces traditional laces with a precision-engineered dial, lace, and guide system that allows micro-adjustable, even tension across the entire foot with just a simple turn. Positioned on the side of the shoe for a cleaner, more modern silhouette, the BOA® dial makes it effortless to put on and take off your shoes, even when wearing a glove. The system locks securely during play, eliminating any slippage or loosening mid-round, and the quick-release function allows instant removal at the end of the day. The BOA® Fit System is purpose-built for performance athletes and delivers a level of fit precision that traditional laces simply cannot match.
The upper is constructed from embossed ECCO Performance leather, a premium material selected for its durability, suppleness, and resistance to wear, complemented by sportive mesh panelling that enhances breathability and reinforces the contemporary athletic design. ECCO tans and processes its own leather in dedicated tanneries, ensuring consistent quality and environmental standards. Inside the shoe, the removable OrthoLite® insole provides long-lasting cushioning that resists compression and maintains its performance properties round after round. Because the insole is removable, it can be washed to maintain hygiene, and its removal also creates additional volume to accommodate a wider foot or custom orthotics.
