Change social media button icons (applied in footer widget)

Hello.

I’ve managed to add Social Media icons (like the ones at the top) to my footer, however, for the life of me, I can’t figure out how to change the icons so that they emulate what I have at the top (Facebook, Twitter, Google, YT, Vimeo, Flickr, RSS).

Here is the code that I have applied to my footer widget:

<ul class="noLightbox social_bookmarks icon_count_7">

<li class="social_bookmarks_facebook av-social-link-facebook social_icon_1">
<a target="_blank" href="https://www.facebook.com/kriesi.at" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Facebook"><span class="avia_hidden_link_text">Facebook</span></a></li>

<li class="social_bookmarks_twitter av-social-link-twitter social_icon_2"><a target="_blank" href="http://twitter.com/#/" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Twitter"><span class="avia_hidden_link_text">Twitter</span></a></li>

<li class="social_bookmarks_gplus av-social-link-gplus social_icon_3"><a href="#" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Gplus"><span class="avia_hidden_link_text">Gplus</span></a></li>

<li class="social_bookmarks_youtube av-social-link-youtube social_icon_4"><a href="#" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Youtube"><span class="avia_hidden_link_text">Youtube</span></a></li>

<li class="social_bookmarks_vimeo av-social-link-vimeo social_icon_5"><a href="#" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Vimeo"><span class="avia_hidden_link_text">Vimeo</span></a></li>

<li class="social_bookmarks_flickr av-social-link-flickr social_icon_6"><a href="#" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Flickr"><span class="avia_hidden_link_text">Flickr</span></a></li>

<li class="social_bookmarks_RSS av-social-link-rss social_icon_7"><a href="#" aria-hidden="true" data-av_icon="" data-av_iconfont="entypo-fontello" title="Pinterest"><span class="avia_hidden_link_text">RSS</span></a></li>

</ul>
