Tim Tebow recently took the phrase "giving the shirt off his back" to a new level when he donated the shoes he was wearing, in addition to 50 other pairs, to a homeless shelter.

The former NFL quarterback visited St. Vincent de Paul in Phoenix late last month and brought the shoes to donate to those staying at the facility, CBN News reports.

When he was leaving, however, Tebow noticed there were more guests than shoes.

Tebow then took off his own pair of shoes and handed them to one of the guests at the shelter.

Steve Zabilski, CEO of St. Vincent de Paul, calls Tebow a superhero.

"If you ask me, or many of our guests, Tim has gone from professional athlete to superhero in just a few years ... His actions off the field are as impressive as any last-minute touchdown pass or game-winning home run," Zabilski told the local news station, KNXV-TV.

Tebow also wrote a list of every guest who didn't receive a pair of shoes during his visit before he left. By the end of the day, the football player had sent each of them a pair of shoes.

In a tweet, Reverend Franklin Graham described the Christian athlete as "a good Samaritan for sure."
