Wow what a huge improvement over the 1st gen! i have worn them for a week now (the red/white/blue). great fit and the tongue feels so much better. no hot spots like the 1st gen (the main issue for me was the corner at the final lace - took like 10 hours to break in). Love the sole and on hard courts great traction, I found on red clay it was not so good as the shallow and non herringbone sole got clogged up fast, lots of shoe banging! But on hard the full sole is great - nice low to the ground feel and the heel holds well. I was in the Babolat SFX's and they are still the most comfortable out of the box by far.
