What is so special about TOMS?

What sets TOMS apart from other footwear brands? Are their products truly unique in any way, or is it just their marketing and philanthropic efforts that make them stand out? I'm curious to know what specific features or qualities about TOMS make them special and worth considering over other options in the market. Do they use special materials or have a unique design that sets them apart? Or is it the brand's mission and values that really make a difference in the eyes of consumers?
