The shoe is wider with every use and wider. Actually have shoe size 39, ordered my Sketchers in size 37, because they would be so big. No stable transition possible with this shoe. Through snow you should therefore not trudge, because you immediately feet wet gets (despite impregnate). Positive to mention is the warm foot in the shoe, but only when dry Weather conditions. Conclusion: much too expensive for this poor quality and the intense smell of these shoes is often unbearable for other people.
