I’m sorry yours have the same issue. My new replacement ones came and they have it too, but not as bad. So, I’ll just keep them.
Hahah now I fear they'll send me a pair with an even worse problem

One foot was a bit better than the other, I could live with it. But the other one was reeaaally disjointed. You could see they were two separated "rubber bands" (can't think of a better term) that should have been merged but something went wrong.
They are very nice, though, aren't they?
