Ok so I bought them on Sunday of this week. I bought Radical Pro. It actually isn't that bad. It has great support and ventilation is actually better than the previous prestige. The Durability, from what i see if you play tennis like almost 4 out of 7 days of the week, you might worn them within 4 months or so. It fit right out the box, comfortable , you could just jump up and down with out feeling the vibration from your feet. It has the Flex Zone that give you no break-in require on the top of the shoe. So far the only thing i dislike about the shoe is the lace, it was too short to hold on to your feet. I actually do recommend these shoe to everyone.
