Pros: Discreet, effective, simple to use.
Cons: I can't blame my knees for bad technique now.
Over the years I've spent quite a bit of money on knee supports and pain killers. It had got to the stage where I could maybe ski for 2 or 3 days before needing to take time off for my knees to recover. When I was skiing, a lot of the time I knew what I should be doing but my knees just weren't up to the job. I'm a bit young for knee replacement work and would like to hold off on that as long as possible.
I've looked at other systems, such as CADS, but they seemed to be a lot of faff, particularly when it comes to riding lifts and they seem to work best if you're skiing in the back seat. The mojos stay inside your ski pants and mimic your legs - they are like a mini exoskeleton. They attach to your boots, have a joint at your knees and then are held around your hips with a corset type thing.
Once you've put them on in the morning (doesn't take long), you can wear them all day without anyone knowing. When you put your ski boots on, you clip the mojos into your boots and that's all there is to worry about. There's a switch at the top of each leg which you can use without needing to take gloves off, and that sets them on or off. Switch them off to sit down, switch them on to ski.
When switched on they get you forward and hold you there. They take the stress out of the knee joints and mean you can stand in your boots at the bar with a big grin on your face.
I'm now out on the hill all day, every day, skiing harder and faster than before, and my technique is now starting to improve too. But most of all, they've made skiing fun again.
