I love Birkenstock, but this particular one disappointed me.
Although it has a nice footbed and doesn't tire you out, the leather cutting at the end (the part that touches around the foot) is bad and without socks it causes a wound.
It is a shoe intended to be worn with low or no socks (and that's how Birkenstock advertises them). Therefore, I find it a big failure for the leather to chafe. I felt it as soon as I put them on and after a 10-minute walk, I already had a bloody wound.
With high socks, it's okay, but this greatly limits (in my opinion) what you can wear them with.

Very beautiful and high quality. However, they are quite wide, they seem like one size bigger than normal. But the design is wonderful. Definitely, this specific brand needs some time for the foot to get used to it.
