Hi,

We’re using FontAwesome to style icons. So you need go to .less file to change

Example: for wishlist please go to file: /skin/frontend/sns_kalolia/default/less/content/listing.less find and replace code:

.link-wishlist {
	&:before {
		.font-awesome (f004, 30px);
	}
}

by:

.link-wishlist {
	&:before {
		.font-awesome (your_icon_code, 30px);
	}
}

Thanks!
