The problem was that the insole of the left boot was stuck and not aligned. Not wanting to risk tearing the insole by repairing it myself, I ordered a replacement. As I expected, the replacement had an identical problem. This time I successfully removed and aligned the insole, after doing the left one I also did the right one as it could have been better. I have now bought Brexton Sketcher shoes from Khol and they have the same outsole and insole and fit perfectly. Big. So you are wondering if Sketchers will pass on shoes with lower quality checks to online sellers/sellers? Because nobody will wear and buy these shoes in the store. The shoes are very comfortable and the quality is excellent beyond their "assembly". I still recommend and be aware that you can pull out the insoles to attach them without tearing them and I probably won't need to buy glue because they are still pretty sticky to the sole.
