Assuming they're the ones Chips had for sale a couple of weeks ago, they're definitely very worn and were (I think) advertised as such.
The braking surface on new Open Pros is machined flat, but having worn a few out to the point of the sidewall bulging, I've always found that they fail gracefully. If it were me, I'd just use 'em till they wear out completely.
