The 10's arrived first and I could get them on but they were much too tight. I have Levi's, Wranglers, Eddie Bauer, Schaefer, LLBean and several brands of jean. I wear either an 8 or 10 in those brands. For that reason I feel they run small. The denim is lighter weight so I'm not sure how they would hold up as both pair were returned. For just riding I feel they would be fine. I did like the rise and the higher back- I wouldn't wear them doing any type of work outside.
