The foam is still in prefect original shape as if they just came out of package but now it has a "memory foam" like squishy feel to it. Did I get a pack of bad foams or is the new "hot ticket" from proline? I've never had a set foam feel like this before!

I have a race day on them plus two practice days and they are really flat right now and feel soft and dead as you put it.
