Unfortunately, flaws in the processing

The shoes look very good, the leather also appears quite high, a total so I'm really pleased. It is a pity that after a few weeks on the right side of the sole of the shoe triggers. This is not, as assumed in a review, sewn, but glued simple. At the right shoe now gapes over a length of about 5cm a gap between footbed and rubber sole. Very sad, even though the shoes are worn by me solely in the office and thus hardly overused.
