Wow!! Love the design. Found on Asics website and now it has GEL-Blast™ 5 but colour wasn't that striking though.
I wear Asics all the time as my regular shoes but never worn an Asics inside court shoe. I looked into the Blast and the Blade and both were out of my price range. I wish I could find a great deal on them in the US.
After researching on gel blast 5 and blast 4 on the net, I cannot find any improvement on the gel blast 5. Some say it is lighter and less bulky but when I held both blast 4(orange) and blast 5(yellow), the weight feels the same. Material, tech, design are the same as well. I'm not sure why Asics called it blast 5 if everything is the same as blast 4.
