Originally, these were camel-colored shoes made as a special order for United Arrows, but they have been dyed. As a result, dye has seeped into the lining, so those who are concerned should avoid them. The dyeing was done by a shoe polishing and repair specialist in Tokyo. The color appears uneven in the photos, but it's not that noticeable in person. The insoles have been replaced at a shop in Tokyo, and some dye from the dyeing process has splattered on them. If you are concerned, I can tell you the shop, and you may want to consider replacing them. An insole, about 1mm thick, has been added. This is why the inside looks new in the 7th photo. The soles are protected with half rubber soles, and thick rubber has been added to the toes. The heels also show little wear, so you can still wear them for a long time. *Shoe trees are not included.
