The positives: they are indeed shock-absorbing and provide good support to the Achilles tendon, they do not slip even on dusty surfaces. They seem durable, I have had them for 6 months and they have only worn out slightly.
The negatives: they easily and quickly develop a strong odor, they do not have good ventilation at all, and their materials, although durable, are very plastic-like. They have a fairly rigid sole for a perimeter player, to the point where they sound like heels on the court. They caused blisters on both of my feet in the exact same spot, below the ankle. They have this protective padding around the Achilles tendon that is completely inflexible and rubs against the foot with every movement, causing blisters. I had to modify the plastic in order to be able to play.
Good shoe if you don't want to suffer from vibrations, but highly overpriced. Maybe they are worth it for 50 or less.
