There are times when we can benefit from some extra help, especially as we age or develop chronic medical conditions.

Nick Manley, a remarkable athlete with a degenerative neurological condition, swears by the Ski-Mojo knee bracing system. The product’s shock absorbing springs reduce the load on his knees, allowing him to continue to race and ski for the entire day without tiring.

I haven’t used it, but I have talked with Nick and at least a dozen other older skiers who tell me that it has made a profound difference in their skiing experiences. Ski-Mojo also helps maintain correct posture while skiing and makes it easier to ski longer.

If you feel you could benefit from some assistance, my strong suggestion is to visit Ski-Mojo’s site.

Now, on a limited basis, there’s another innovative approach to helping your knees. I wrote briefly about it a few months ago, when the company started advertising. The product, being developed by Roam Robotics, is called Elevate. It is a computer-influenced soft exoskeleton that utilizes pneumatics to assist movement in your legs and knees.

It may sound sci-fi, but it’s for real. Starting March 9, the company is making Elevate available on a unique demo basis in three locations: two in Lake Tahoe; one in Park City.

Rent the device, and Roam will arrange for one of its trained ski hosts to accompany you for a few runs or for the entire day, based on your preference. If you’re staying within a certain radius of their facilities, the company will deliver the device to you the night before and provide enough orientation so you’ll be good to go the next morning when you meet your ski host on the hill.

If this sounds a little protective, it is. As a product, Elevate is ready for prime time, but the concept is so new that the company wants to provide hands-on education about its use. It also wants to collect information about customers’ experience to improve future versions. All of this is to assure a smooth roll-out when it ramps up production and makes Elevate available more broadly in seasons to come.

The cost for a one-day demo is $109, which includes drop-off and ski host services. If you are in the Tahoe or Park City neighborhoods and want to try an entirely different approach to protecting your knees and getting more out of your ski day, this is your opportunity.
