We're going to go out on a limb here and say that Keen® Elsa Slip-Ons are destined to be the most comfortable lace-free footwear you've ever stuck a foot into. There's lots of reasons why, starting with the lightweight canvas upper and Keen's distinctive wider toe box that gives the forefoot more wiggle room. Inside there's a real rarity: a removable, metatomical dual density PU footbed that shapes itself to fit your foot for customized cushioning. The breathable canvas lining keeps the shoe's inside environment feeling fresh, and Cleansport NXT™ odor inhibitor squelches not-so-pleasant smells. And a flexible, non-marking vulcanized rubber outsole takes high-mileage days in stride.
