I think many of my whites and wescos have had this in various spots and those boots are built sturdy. I dont know why it happens but i dont think it impacts the integrity of the boot idk if it will get worse. Mine never really did.View attachment 378036
Is this sort of separation in the heel par for the course or a defect? This is the second pair of boots ($600 and $900) that I’ve had this happen to fairly quickly.
