Since quite compresses over time the lining of the shoes and at some point will be stained - unfortunately you get no suitable warm lining for shoes when ordering - I bought the latest model "Croca Baya Lined".
For optics shoes, running comfort etc. I have to write much - it has also been compared to the predecessor models (see above) changed nothing.
However, the synthetic lining "Baya Lined" in the current model is absolutely uncomfortable !!
The first impression when you see the shoes is very positive. After a short gestation period in the apartment (normally heated!) Be your feet in no time very "wet". I'm with the little shoes in our apartment on the way and sweating almost never on the feet !! I also tend not to cold feet - have in themselves very "unproblematic" feet to cope with all the shoes!
The shoes I like the other models - mentioned above - (ie barefoot) worn without socks. Power yes even with Velcro / warm lining sense, otherwise you do not feel it, yes!
Unfortunately I had the shoes very quickly off again because the food at extremely sweaty feet (not warm feet !!) leads. Very unpleasant. I hope I get the shoes back retouniert.
