These are Danner side-gore boots featuring waterproof and breathable Gore-Tex material. They are built as sturdy as work boots. I've used them a few times for farm work, but they still have plenty of life left. The soles and side gores can be replaced, so with proper care, they might last a lifetime. The size is US8EE, so they should fit people with wide feet at 26cm, or people with regular width feet at 26.5cm.
