50 size, real 48-49, not bad. The insole was not very expected. The necklace is really very strong. Walking at a temperature of from 5 warm to 20 is quite comfortable. Moreover, the legs in them almost do not fit. Humidity passes quickly, it is not very comfortable during rain. The Ergonomic is like that... for daily wear hours, I do not recommend it, only for some time, the legs are tired. Not the worst far away, they really liked it, but the sole and Ergonomics were disappointed. After another shot of r..it, well running around the sleeve, nails, and similar - easily moved. I't say that they are not sick, but you won't call them sick. Specific shoes, time will show.
