Most of the customers/players I know who got them said they are decent, but have swapped to other skates or switched back to their previous skate. I tested them and they seem ok. Nothing special or significant stood out to me.
Positives:
Updated lacing system allow for more forward flex
Updated liner and foams are nicer than previous generations
Negatives:
Carbon Curv doesn't seem durable, many of the Hyperlite skates that come into the shop are in bad shape.
Updated tongue has a very stiff insert that many people find uncomfortable
Carbonlite runner (optional) is trash. Stay away from it.
Neutal:
Updated outsole is supposed to allow more flexion and torsional flex. I did not notice this when testing them.
Skate is supposedly lighter than previous generations. While it does weigh less than the 2X Pro, its heavier than the 1X. We are talking about a very small margin, so that that with a grain of salt.
