I ordered this size is the husband who is 7,5 US in all brands. the brand pajar stated that 7.5 = 40. When we received these shoes, they saw that they were a child, was able to wear them only I wear women's size 8.5. and yet, they are on a very narrow foot, keep in mind that within the fur. Overall, the quality is very good, the label indicates the manufacturer of temperature-20C zachit warm, quality soles suggests that it should not slip.
