Foot Kayaks

No, they won't let you walk on water but, rather, in it.

Down Memory Foam Slippers

Unlike other down-filled slippers which can only be worn indoors, this remarkably warm footwear can also be worn outdoors, keeping you comfortable with the unmatched softness, light weight and warmth of genuine duck down.

An elasticized collar extends above the durable rip-stop nylon outer shell to keep ankles warm and durable suede sidewalls help the slippers keep their shape.

The moisture-wicking micro-fleece inner lining ensures that your feet remain dry and the weatherproof outsole provides an effective barrier to water and a skid-resistant tread for sure footing.

Intricate quilting throughout the outer shell keeps the down securely in place.

Women get their choice of red or gray while men — well, men can have any color they like... as long as it's gray.
