These boots are really sturdy! The rubber is really thick, slightly narrow sizing though. The soles are really thick and give great traction, I wear them with thick fuzzy socks when its icy. Also, I was wearing these when I got hit by a car while in a crosswalk and these protected my lower legs and ankles from getting scratched up by the pavement like my knees and elbows did. They are a little marred from the impact but theres no cracking in the rubber so I still use them.
