I bought sandals for 398 yen ($3.98 €3.06) at a hardware store Homac. Last year I bought the same sandals but they were broken shortly after purchase. Despite this thing, I challenged to buy spares. I have no idea how long they will work. Actually 398 yen ($3.98 €3.06) is very cheap price for sandals. It is almost the cheapest price. I can not complain about its quality. There were black sandals and blue sandals at the store. But for my size, only brown one was remaining. Last year's broken sandals were the brown one.
