Hey Mike thanks for the info. It's just aesthetically annoying and the other shoe actually have the welt on the outside but the crack is much less pronounced (pic below).

Thinking whether I should return it or not.
If you are unhappy with them and are able to return them, then you should. If they are an unobtainable design, the pain threshold before returning increases. What exact pattern is that? Is that the Perf Tip Balmoral in Black or Color 8? Interesting that it's on the outside on the other foot.
