The icon is described as human footprints. It shows two human feet that are symmetrically side-by-side as if belonging to a person standing at attention. The toes are oval shaped and separate from the feet like in a real foot print.
This is a Footprint icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
