Rugged sole, fur on the inside holds up well to daily wear in winter. There's hardly any visible wear on the rubber soles after 2 winters of daily wear (November - March). I treated with Ugg suede waterproofing spray and they stayed dry in the snow and did not get salt stains.

In temps below 0* Fahrenheit, my toes did still get cold after a bit of time outside. At those temps I usually put on my foam Moon Boots haha!
