Ex-New York Giants lineman George Martin went through 24 pairs of shoes and lost 40 pounds before finishing his cross-country walk Saturday, raising $2 million along the way for sick 9/11 rescue workers.

Martin ended his nine-month, 3,020-mile trek at Embarcadero Park, where he was met by police officers, firefighters and other NFL alumni.

"I feel like a million bucks," Martin said. "Other than a blister that I have on my left foot, I'm in great shape."

He began the walk in New York on Sept. 16 to draw attention to the plight of rescue and recovery workers who developed respiratory problems after working in the dusty ruins of the World Trade Center.

He trudged through rainstorms, winter ice and brutal heat, and the trip took five months longer than expected. He averaged 22 miles per day and burned through 80 pairs of socks.

A great achievement and for a good cause.
