Much like the noses on certain brand sports cars you can usually identify Keen shoes by the distinctive toe bumper but this supportive San Clemente keeps the top down without losing any grip on slick surfaces. Keen used a siped outsole design made from carbon rubber to optimize your traction especially when you're wading in rivers or walking along rocky seashores. The washable polyester webbing has a durable buckle closure that helps secure your foot firmly giving the San Clemente better river rafting potential than some slip-on sandal designs. Best of all Keen tweaked the midsole with an internal shank along the middle for support while adding flex grooves through the forefoot. If you're looking for a sandal design that's a little more open up top but you don't want to compromise key support the San Clemente is a smart fit.
