Can these be used for skijoring?

I like to try new things and see what might work. In this case it's about new inlines for skijoring. Or this is more of roller skis. It's fun to both try to find something for myself that might work better than what I already use today. What I would like to find or create is a pair that could work when the ground is a little softer like they usually are in a normal riding arena. Please let me know if you like to see me try something like this, either in the comments field on my social media or DM me. It's also fun to hear what you like or appreciate less. 

Otherwise, I, the horses and my family are doing well. I've been out at a dressage competition with Zin Fire where we took 2nd place! I've taken it pretty easy with the competition. but I'm planning to start the eventing season in mid-May. That's all for today. Stay Horsey!
