As if he couldn't be much more of a heartthrob than he already is, Zac Efron finds more ways to tug every person's heart strings.

In a recent campaign by sock company Bombas, the 30-year-old actor helped ring in the 5 millionth pair donated in just a simple wink.

As socks are said to be the No. 1 most needed clothing item at homeless shelters, Bombas donates a pair of specially made socks for every pair purchased.

"Go team Bombas," Efron said on Instagram.
