Bought these hoping that I may be able to get out more with my second baby, Canada can be very cabin feverish in the winter if you aren’t getting out. These were a game changer for us, I used on several Nordic trails with ease as well as navigating back alleys in the city neighbourhoods where snow banks are no longer a problem for us. You need snow to run them on and they will scrape if there is sand/gravel. I found even just using on the front wheels in city was enough to make getting around easy. Our temperatures get pretty cold carrying her is not an option, so now my baby is wrapped up and cozy. We had a slight accident where we snapped one of the front supports and premier skis replaced without question free of charge, they wouldn’t even allow me to pay postage, fantastic customer service.
