It`s really light for a ballestic and very comfortable.
I think Rafa's shoe designer got together with KD's (Kevin Durant) stylist and created this shoe. I love the styling and beautiful pink color to boot. It feels slightly lighter than last year's Ballistec and maybe a tad longer albeit it fits just right. A very comfortable shoe and has lots of cushioning. Definitely would buy another one if it comes in turquoise color similar to what Rafa wore spring of last year.
This shoes is very light and is it really good for playing tennis for several hours.
