Yes, they are leather, but the €79 I paid for them is not worth it. The amount of leather in the sandal is not enough to justify such pricing. Also, the sole of the sandal is not durable; the rubber has worn out since the first time I wore them, causing them to slip. The rubber could be reinforced to withstand daily use. For next summer, I will definitely have to take them to a cobbler to get them fixed.
