I have worn resolution 4 & 5. These are so much better, Lighter and more comfortable. I feel like they bend more easily so it's easier to stay on my toes. Love them!
I play five to six days a week (doubles, mostly) and I move a lot on the court. These shoes have a nice low profile that makes you feel stable but quick. I have a very narrow heel, and I love the way these shoes hug my feet. They feel like a great running shoe made for tennis. Players with wider feet would probably not like these.
I love this shoe. Out of the box comfortable. No break-in time needed. It is light with fabulous cushioning. I have the "speed" in every color.
