I own several pairs of Ecco golf shoes. Ever since I switched to this brand, I have not been disappointed! The material is great. Their shoes are very comfortable right out of the box, and having Gore-tex can't be beat! The new tongue design on these particular shoes is also a nice improvement. The tongue fits well inside the shoe and is not bulky or prone to drifting. The toe bed of the Biom 4 is wider and a better fit for me than the more narrow s-three line, and I also find the tread pattern to provide plenty of traction, even on wet or damp grass. If you haven't tried Ecco before, give the Biom 4 a try, especially if you can get them for under $100!
