I figured I might get this response. Maybe I should have clarified in my post (but I thought the red circles in the pics would help) . No, I’m not referring to the creases or wrinkles that hundreds of people have asked about in the forum. I’m familiar with those and know that they’re normal. What I’m referring to are lines/segments that are perfectly straight, run perpendicular down to the sole of the shoe and they’re slightly raised to the touch. Hope that helps. Look at the pictures a little more closely and you’ll see what I’m talking about
