I've noticed after a couple of weeks of wear, the leather plies that form the sole are starting to slightly separate. I emailed Red Wing and they told me slight separation is normal. This concerns me because these boots are almost brand new. I'm tempted to send them back to Zappo's for a refund.
I've had issues with Red Wings already. I initially bought the Beckman chukkas. After a few days, the rubber heel began to separate. I exchanged them for another pair and the same thing happened. After two pairs, I exchanged them for the six inch boots. I was hoping the boots, with its solid rubber heel, would solve this problem. Now I have an issue with the sole.
