They did not have the expected durability and quality of construction. I wore them for just two winters and then threw them away. From the first winter (2022-2023), the inner leather wore out at the points that came into contact with the sole of the foot. They barely made it through the second winter (2023-2024), at which point they were thrown in the bin. There was also an unpleasant, mild smell at the worn area of the toes indicating poor quality materials.
For this year (winter 2024 - 2025), I chose leather Boxer, and so far (01/11/2025) I am very satisfied with them....
For your information: I have been wearing leather slippers for many years. Always with clean feet and fresh socks when I return home. Also, used only indoors and with care!
