I thought I could live with it, but my OCD is getting to me. Would you return these seconds brown shell strands? I got them during the $299 sale. As you can see there is excess material at the stitching of the cap. It is not as noticeable when looking down from normal viewing distance. The right shoe is fine. It is just this left shoe with too much material that isn't glued down.
If you hadn't described the problem, I'm not sure I could have spotted it from those photos. These are 2nd, you have to remember so you cannot expect perfection. Also remember the commonly made point around here that your feet will generally be further away from everyone's eyes than in close-up photos and usually your feel will be moving. No one will notice. It may bug you indefinitely, though, so you need to make the call.
