Best Answer

I suggest you load the footmisc package with the option hang to achieve your objective. The distance between the footnote marker and the start of the footnote text is determined by the parameter \footnotemargin.

The following screenshot shows just the footnote produced by the MWE given below.

\usepackage{cmap}               
\usepackage[T2A]{fontenc}       
\usepackage[utf8]{inputenc}     
\usepackage[english,russian]{babel}
\usepackage{multicol}

\usepackage[hang]{footmisc}
\setlength\footnotemargin{1em}  % default value: 1.8em
