Definitely lighter than the resolution, but noticeable less support than the resolution 4 and 5. Depends on your needs ... I need a little more support so I prefer the resolution. But still a great shoe ... asics makes the most comfortable tennis shoes I've used, and I've tried 'em all!
This shoe is similar to the Nike Vapors in weight, but this one is a lot more comfortable. Its one of the lighter shoes out there, which helps with accelerating from a stop. I have owned Prince T-series shoes and those guys are like wearing bricks on your feet, so switching to these Asics is like wearing feathers in comparison. Overall, these shoes are light, very comfortable, require zero break-in, and perfect for a normal foot. (4.0 NRTP)
I purchased these shoes because asics are the most comfortable tennis shoes out there. The issue that I had with my prior pair was their weight and that issue has been fixed very well in these asics. Overall great shoe.
