Hi @SiliconValley 

Chjeck this one. 

From you Admin page, go to Online Store > Themes

Select the theme you want to edit

Under the Asset folder, open the main.css(base.css, style.css or theme.css)

Then place the code below at the very bottom of the file.

@media screen and (min-width: 750px) {
  .footer__blocks-wrapper .footer-block__details-content .list-menu__item--link:hover,
  .footer__blocks-wrapper .copyright__content a:hover {
    text-decoration: none;
  }
}

And Save.

Add some !important. 

Like this .

@media screen and (min-width: 750px) {
  .footer-block__details-content .list-menu__item--link:hover,
 .copyright__content a:hover {
    text-decoration: none !important;
  }
}

And Save.
