Our socks are made by DeFeet. All the socks on this page have a 5" cuff height. They're made from Merino wool, so they don't build up stink as badly or quickly as other fabrics, and being merino you can machine wash them, though we recommend air drying them. Wear them riding, wear them with your "I'm A Grown Up!" suit, or wear them with a loosely drawn robe and nothing else.
And don't forget: we also have tall socks for wearing with boots and/or 'knickers'. Find them here.
