Made from premium materials, the Ecco Biom G3 Boa Golf Shoe offers excellent stability from a spiked shoe, complete waterproof protection and a precise dialled-in Boa® lacing system. This new Biom G3 Shoe is the latest edition to Ecco\'s BIOM range. BIOM, standing for \'biomechanical optimisation\' is designed to help you move efficiently and powerfully, encouraging your feet and lower legs to strengthen with every step - this is achieved by guiding the foot to activate its own natural systems for shock absorption and motion. Crafted from ultra-soft Dritton Nappa calf leather with a GORE-TEX® waterproof membrane, this shoe is guaranteed 100% waterproof under normal use. This is the Boa® version of the Biom G3, a micro-adjustable system which provides a better connection to your shoe - improving stability, control, and power. Underneath, eight Zarma-Tour® spikes, together with hybrid cleats on the toe and rotation line provide increased stability and optimal grip and additional stability comes from Ecco\'s X-Tensa Invisible Technology, linking the sole of the shoe to the laces via internal enforcement. Inside, for optimum comfort, a removable Ortholite inlay sole also offers long-term cushioning, moisture moving properties, increased breathability and the option of extra width if it is removed. Ecco prides itself on using quality materials and construction methods, and the Biom G3 Boa Shoe encompasses this, offering a premium shoe for the serious golfer looking for ultimate comfort and performance.
