does anyone know what theme this is?

thus is probably a strongly customized default theme, as you can see from the line in the html code:

<style type="text/css" media="screen"><!-- @import url( https://pumpsshoes.org/wp-content/themes/default/style.css ); --></style>

who need a template like this? Plus it is not wordpress…

Ah thank you.

The default theme it looks like it have been modified after one of Brian Gardner’s theme. It looks very much of his style of css coding.
See example:

body {
	background: #FFFFFF url(images/bg.gif) repeat-x;
	color: #202020;
	font-size: 12px;
	font-family: Arial, Tahoma, Verdana;
	margin: 0px auto 0px;
	padding: 0px;
	}

#wrap {
	background: #FFFFFF;
	margin: 0px auto 0px;
	padding: 0px;
	}

/************************************************
*	Hyperlinks									*
************************************************/

a, a:visited {
	color: #BF0283;
	text-decoration: none;
	}

a:hover {
	color: #000000;
	text-decoration: underline;
	}

/************************************************
*	Header  									*
************************************************/

#header {
	width: 960px;
	height: 110px;
	color: #000000;
	font-size: 16px;
	font-weight: normal;
	margin: 0px auto 0px;
	padding: 0px;
	overflow: hidden;
	}
