These are different sized sheepskin boots. The right boot is size M and the left boot is size L. The difference in length from the toe to the heel of the sole is about 1 cm. Please check photo 5. Although they are unused, they have been in storage for a while, so I've marked them as "like new." If you prefer a more spacious fit for your left foot, please consider these. They will be shipped in a simple package using a box I have at home.
