These have been alot of fun! They kept falling off at first, but I realized I had been putting them on wrong. Once I figured out the right way, they have stayed on! I used them on a packed down trail, and the snow once it was a bit harder and didn't sink in so much. One of my favourite things has been to strap on ice skates and push the stroller with the skis around the rink or skating trail. I HIGHLY recommend!! I find them a bit challenging and time consuming to put on, but I'm sure I will get better with practice. I'm also not sure how to navigate crossing a street, for example from the trail to my house. I scraped the skis along, but it can't be that good for them. Some advice or solutions would be helpful! One other thing I found useful is to lock the front wheels of the stroller if you have that option. The stroller skis have brought me so much enjoyment to this winter!
