I have played tennis and squash in the Evo, Neo and Aqua models. The Aqua is very low to the ground and comfortable. The Evo and Neo have a slightly thicker and narrower sole, so they are slightly less "barefoot" feeling. But they have better traction, if you play on clay, and more durability because of the thicker sole I would guess. By the way the Aqua is now called Aqua lite and is more light weight than the old model. Hope this helps.
