On April 28, Tom Wallisch will participate in the 23rd annual Walk MS in Salt Lake City, Utah, to help raise funds and awareness for multiple sclerosis.

Wallisch, whose aunt suffers from the disease, plans to walk the three miles in his ski boots to, according to a release, "help demonstrate what it can feel like to walk in the shoes of someone living with MS."

"Helping to find a cure for multiple sclerosis is important to me," Wallisch said. "My aunt has been living with the disease for many years and my family has participated in Walk MS events since I was a kid. I know these events make a difference."

Wallisch is the 2012 Winter X Games Aspen Slopestyle gold medalist and this year's top ranked men's slopestyle skier in the Association of Freeskiing Professionals.

Some 4,000 others are expected to participate in the Salt Lake City walk and many thousands more at the more than 500 MS walks held annually around the U.S.

"MS can stop people from moving and it could be easy for all of us to take movement for granted," Wallisch said. "I am fortunate to compete in an amazing action sport and want to lend my support to help not only my aunt but everyone impacted by this disease."
