A revolutionary hybrid model that blends on-course performance with off-course style, ECCO S-THREE is a game-changing design that delivers premium comfort from the tee box to the clubhouse and beyond. Uppers are crafted from thick ECCO SOFT CALF NAPPA leather made in ECCO's own tanneries, with 100% waterproof GORE-TEX technology keeping feet dry and comfortable in all conditions. A double layer of neoprene in the collar and heel provides increased padding for additional wearing comfort throughout the swing while ECCO FLUIDFORM Direct Comfort Technology ensures a finely-tuned balance of cushioning and rebound; this creates an integral, flexible and durable bond without the compromises common with conventionally stitched and/or glued assemblies.
