The ECCO GOLF BIOM® G5 combines outstanding athletic performance with a progressive, modern design. This new generation of the BIOM® family is equipped with ZARMA-TOUR® spikes paired with innovative hybrid outsole zones for exceptional traction and stability across all course conditions. The updated BIOM® last promotes natural movement while delivering superb support, stability, and a precise, locked-down fit. GORE-TEX technology delivers 100% waterproof protection, keeping your feet dry in all weathers, while embossed ECCO Performance Leather and sport mesh elevate the contemporary, athletic aesthetic.
Built on an updated BIOM® last, the Natural Motion technology is engineered to work in harmony with the natural biomechanics of your foot. It encourages a more natural gait and movement pattern throughout your golf swing and during your walk around the course. At the same time, the construction provides firm arch support, lateral stability, and a snug, precise fit that keeps your foot secure at the moment of impact. The result is a shoe that feels like a natural extension of your foot rather than a rigid piece of equipment.
The ZARMA-TOUR® spike system is purpose-built for tour-level grip and durability. Each spike is strategically positioned to maximise ground contact during the golf swing, delivering exceptional traction on wet and dry fairways alike. These spikes are complemented by innovative hybrid outsole zones — areas of the sole that blend spiked and non-spiked construction — to provide a stable, balanced platform under every part of your foot. Whether you are walking 18 holes or standing firm through a full driver swing, this outsole combination keeps you grounded.
The GORE-TEX membrane integrated into the ECCO Biom G5 provides a guaranteed 100% waterproof barrier, keeping moisture out across the entire upper. Unlike simple water-repellent coatings that degrade over time, GORE-TEX is a proven and permanent membrane technology trusted by golfers worldwide. Crucially, it remains fully breathable — excess heat and moisture vapour from your foot can still escape outward, so your feet stay comfortable and fresh throughout even a long round in cold or wet conditions. Morning dew, light rain, and damp rough are no match for this level of protection.
X-TENSA INVISIBLE TECHNOLOGY is a structural bonding system that seamlessly joins the shoe's upper to the midsole without any visible external reinforcement. This hidden connection creates a unified, rigid structure that resists lateral twisting forces during the golf swing — forces that can compromise both accuracy and comfort over repeated use. The invisible nature of the technology means the sleek, modern silhouette of the Biom G5 is completely uninterrupted, while the performance benefits of a reinforced connection are fully preserved under the surface.
The upper of the Biom G5 is crafted from embossed ECCO Performance Leather — a premium material developed specifically for sport and high-wear applications. ECCO's own tanneries produce this leather to exacting standards, resulting in a surface that is supple yet durable, resistant to scuffing, and capable of maintaining its shape through hundreds of rounds. Sport mesh panels are integrated into the design to improve breathability and reduce overall weight, while also contributing to the contemporary, athletic aesthetic that sets the Biom G5 apart from more traditional golf shoe designs.
The OrthoLite® insole is a high-performance footbed designed to provide long-lasting cushioning that does not compress and flatten over time like standard foam insoles. Its open-cell foam structure actively wicks away moisture and promotes airflow inside the shoe, keeping the underfoot environment dry and comfortable. The insole is both removable and washable, making it easy to maintain hygiene over the life of the shoe. When removed, it also creates additional volume inside the shoe — useful for golfers with a wider foot or those who prefer to use a custom orthopaedic insole for added support.
