Jason that's the same Question I was going to ask. I have a brand new pair by that I mean less then a month old. I was talking to a guy in the Poulsbo fly shop the other day. He said he picked up a pair when the first came out and the soles kept comming off on them. I'm hoping they fixed that. $149.00 is a lot to drop on a pair of boots that the soles fall off and you can't even dance in them
The newer ones have those tabs that look like they must click into the sole somewhere. It looks like a much better design, but I've never used them.
I originally got korkers thinking it would be so great to have the interchangeable soles. I have almost never found it necessary to change the soles out. Next time I buy some boots, it will be some plain old sticky rubber sole boots, maybe with cleats.
