That's just chromexcel. It can be like that, seen it on tons of shoes. One reason I don't always love that leather, I had a pair of J Crew Indys that were so bad after one wear I returned them as defective, they just had a horrible piece of Chromexcel on them...and I was expecting the typical Chrimexcel "character". Those don't look too bad to me though, I wouldn't be concerned by those.
