The Zg21 is my favorite golf shoe and I own several pairs. This pair fit just as well as my others, but after one round in clear weather the fabric on the upper was covered in dust and dirt. It took a lot of effort to clean the material with Blue Dawn to remove most of the dirt and give it a decent look again. However, the second time I wore the shoe I had the same mud issues so I only wear the shoe occasionally and am disappointed that Adidas have released a golf shoe with such poor performance.
