Nevertheless, I forgive only 1 star, for two reasons:
1. not to use as slippers. It starts up a lot of water in the shoe that does not expire by itself and needs to be emptied with difficulty. I do not understand how a rubber boot is designed the swimming pool, shower, beach etc is unsuitable.
2. I get very short time (10-20min) extreme sweaty feet in your shoes. The feet are warm and humid, the air holes are not sufficient, thereby wearing unfortunately quickly unpleasant. I do not have excessively high room temperature (18-20 ° C) and no floor heating, so I never run barefoot or in socks in the apartment. I also get in sneakers sweaty feet, but only after a long gestation period. In the old rubber-flops I had the problem not, perhaps because they were less footbed and much more open. As Slippers thus the Crocs fall out as well.
