あなたのソースコードは少し長いです..これを試してみてください...あなたのhtmlの頭の中で
<!-- Foundation 3 for IE 8 and earlier -->
<!--[if lt IE 9]>
<link rel="stylesheet" href="/css/foundation3/normalize.css">
<link rel="stylesheet" href="/css/foundation3/foundation.css">
<link rel="stylesheet" href="/css/foundation3/app.css">
<![endif]-->
<!-- Foundation 4 for IE 9 and earlier -->
<!--[if gt IE 8]><!-->
<link rel="stylesheet" href="/css/foundation4/normalize.css">
<link rel="stylesheet" href="/css/foundation4/foundation.css">
<!--<![endif]-->
そして、bodyタグを閉じた後:
<!-- Foundation 3 for IE 8 and earlier -->
<!--[if lt IE 9]>
<script src="/js/foundation3/foundation.min.js"></script>
<script src="/js/foundation3/app.js"></script>
<![endif]-->
<!-- Foundation 4 for IE 9 and later -->
<!--[if gt IE 8]><!-->
<script src="/js/foundation4/foundation.min.js"></script>
<script>
$(document).foundation();
</script>
<!--<![endif]-->
