Instagram is filled with a lot of silly hashtags and trends like selfies and those ridiculous belfies, so it's refreshing to see a viral trend emerge on the photo sharing network that's actually good for something. Enter TOMS' One Day Without Shoes campaign.
The shoe company is using the #WITHOUTSHOES hashtag on Instagram to help the company go viral and provide much-needed shoes to less-fortunate children around the world.
To get involved, all you need to do is take a barefoot photo of yourself and post it to Instagram with the hashtag #WITHOUTSHOES. For every photo posted, TOMS will give a new pair of shoes to a child in need.
