After a period of 5 months, I would say that it is comfortable for walking, but only on soft surfaces, on beaches without many pebbles.
If thorns and other grass stick to the fabric, they are not easily removed.
For a sandy beach and in water, it is relatively okay.
The sole came off after 4 months and I had to glue it back on.
I wear size 43 in sports shoes and I bought these in size 42.
In the end, I would not recommend them.
