Sixteen-year-old Matthew Walzer's heartfelt letter to Nike's CEO, Mark Parker, is quickly spreading across Twitter through the hashtag campaign #NikeLetter. Walzer posted the letter on his blog Tuesday afternoon, hoping to make Parker aware of a "great need" for supportive, easily-fastened shoes for people with cerebral palsy.

Walzer was born two months premature, and when he was diagnosed with cerebral palsy, the country's top doctors told his parents that he would never be able to walk. Against all odds, Walzer can walk with the aid of crutches and his Nike basketball sneakers, which provide ample ankle support.

But Walzer has flexibility in only one of his hands, explaining that cerebral palsy stiffens the body's muscles. As a result, he needs someone else to tie his shoes for him.

"I am always searching the web for any type of shoe brand that makes athletic shoes that provide good support, are self-lacing and are made for everyday wear or for playing sports," Walzer writes. "I hope that...Nike will consider being the forerunner in producing athletic shoes that will make [a] difference in the quality of so many lives."

Matt Halfhill, of the shoe blog Nice Kicks, wants to make sure that Parker sees Walzer's letter. He said that for every retweet of this post, containing a video of Halfhill explaining the campaign, Nice Kicks will send an orange postcard addressed to Parker with a link to Walzer's letter.
