Reply To: Change social icons

In this case you need to override file basel/woocommerce/content-single-product.php and replace this line

<?php echo basel_shortcode_social( array( 'type' => 'share', 'style' => 'colored' ) ); ?>

With this one

<?php echo basel_shortcode_social( array( 'type' => 'share', 'size' => 'small' ) ); ?>
