Drawing on the success of our BIOM HYBRID 3 group, we've created a new model, featuring an updated, state-of-the-art outsole. The ECCO BIOM Hybrid 4 is made in durable ECCO leather with a slick, micro-perforated embossing and GORE-TEX waterproof technology to keep your feet dry even in wet conditions. The new ECCO MTN GRIP outsole features our signature FLUIDFORM™ Technology, as well as a smart-looking PU midsole with TPU inserts on either side that securely hug your foot and offer added stability while you're on the green. The elevated appearance and understated design will ensure you look good on and off the course.
