When dressing for formal events, your socks need to be up to par with your suit - the great thing about Falke 's 'No. 4' pair is that they're also durable enough for every day, too. They've been made in Germany from a soft, lightweight silk-blend with reinforced stress zones to keep them from wearing out. Stock up with a few black ones, too. - - Midnight-blue silk-blend - Reinforced heels and toes - 92% silk, 8% polyamide - Machine wash - Made in Germany
