This is a very expensive shoe. It is quite narrow so people with wide feet might have to try another shoe. I have used mine for a year, and it was fully functional, but I decided to buy a new pair and keep the old ones for the gym. I play about 8 hours a week, which means they are very durable. They have Asics Gel techology which is used in running shoes for cushioning. They are quite cushioned compared to many other shoes. The grip is excellent. A mesh net in the bottom of the shoe should provide breathability but I have not felt any difference compared to other shoes. A good thing is that they do not smell bad after one year of heavy use! Quite incredible.
