As I wanted to govern where and how the social share buttons appeared with my WooCommerce store I opted to inject them by hand opposed to purchasing a plugin or paying someone else. Again this is something that can easily be added to your theme’s functions.php (preferably within you child theme and not your main theme, so changes are persistent)

add_action('woocommerce_share','wooshare');
function wooshare(){
echo'
<div class="fb-like" data-href="'.get_permalink().'" data-layout="box_count" data-send="false" data-width="100" data-show-faces="true" style="display:inline"></div>
<a href="https://twitter.com/share" class="twitter-share-button">Tweet</a>
<g:plusone size="tall"></g:plusone>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
<a href="http://pinterest.com/pin/create/button/?url='. urlencode(get_permalink()).'&media='.urlencode(wp_get_attachment_url( get_post_thumbnail_id() )).'&description='.apply_filters( 'woocommerce_short_description', $post->post_excerpt ).'" class="pin-it-button" count-layout="horizontal"><img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" /></a>
<script type="text/javascript" src="//assets.pinterest.com/js/pinit.js"></script>';?>
<script type="text/javascript">
  (function() {
    var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
    po.src = 'https://apis.google.com/js/plusone.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
  })();
</script>
<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=281787978603249";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<?php
}

This adds Facebook, Twitter, Google+ and Pinterest buttons underneath the ‘Add to cart’ button on each page
