At first, they are somewhat difficult to fit,
they are better without socks.
Over time, after 5-6 uses, they mold to the foot and are comfortable.

Guaranteed like Clarks (as well as Geox). 3rd pair, same as the best for summer. Comfortable and cool. I wear it all day

In its positives: Extremely lightweight, very good for posture, and a beautiful shoe.
In its negatives: A huge issue for me is that it doesn't hold the heel at all, resulting in not only the feeling that it will slip off at any moment but also causing friction and injury on the foot (specifically the Achilles tendon), which doesn't stop in any way. It should be noted that I walk at least 6 km daily (to and from work) at a fast pace. If someone wants them only for long hours of standing or for short walks, they will be very comfortable despite the aforementioned issue I mentioned.
