Thanks for the info, I sent the shoes back today after talking with Tony
I've had probably 15 pairs of CXL shoes, nothing creased anything close to this even in areas of wear. This creasing is an issue that has been discussed quite a bit on this forum and for all kinds of leathers. The creased area definitely felt thinner and is quite a large area. If it was a small section that would be understandable but I feel this should have been noticed when the leather was cut for the shoe. Maybe I'm just overly picky.
Service has been great so far, but one shouldn't have to deal with the service if shoes didn't have an issue in the first place. I'm sure this is an isolated issue as most other shoes in this thread look amazing but it's an issue nevertheless.
A recent post with some good info:
I've yet to come across a boot/shoe manufacturer who have no issues with their products from time to time, that is a given when working with leather but there is a way to go about things when a rare problem does arise.
