CONSCIOUSLY CONSTRUCTED
FOR BETTER ADVENTURES

Every product has an impact. And we’re on a long,
long journey to lighten it.

  • PFC-FREE WATER
    REPELLENCY

ECO ANTI-ODOR

We’ve turned to nature to eliminate pesticides and biocides from going into the environment. Our footbeds are infused with probiotic technology that naturally breaks down odor in sweat without heavy metals or hazardous chemicals.

PFC-FREE WATER REPELLENCY

Perfluorinated Chemicals (PFCs) are commonly used to repel water on outdoor gear. But these compounds are suspected carcinogens and persist in the environment, so we’ve switched to alternative chemistry that’s safe yet still effective.

Splash in the puddles, run to the waves.

  • CNX
    We’ve shaved an entire line of footwear down to 10 oz. each, but kept the protection that made us famous. It’s addition by subtraction.

    This internal support mechanism is anatomically engineered to provide excellent arch support and cradle the natural contours of the foot.

  • Great sandel for daycare

    Most daycares and summer camps require closed toe shoes for playground safety. These are the most comfortable for little feet! From start of the day to the end these are great, breathable and durable.

    Always the summertime go-to shoe!

    This is my boy's 4th pair of the Newport sandal. He keeps on growing and these keep pace with him very well. Great for kayaking, ocean adventures, running through the hose, biking, and all. Sturdy, good support for his foot, and he just grabs them as the go-to shoe.

    My son Loves these shoes!

    I gave it four stars because the only issue I had was that we paid extra to get them here before camp. However, there was a delay and they still did not arrive in time even though we paid to have them shipped quickly. Other than the service, the shoes are awesome. In fact, we went out locally and bought him a new pair the day before camp. So, now he is super excited because he has a blue and red pair. They are great shoes. He had a pair that he grew out of, and they are super durable.

    The only shoe we need this summer

    My toddler is always on the go- running, climbing, exploring the streams... these shoes are easy on and they stay on. The rubber is good on rocks, and they have been easy on my daughter's feet- she can be prone to blisters but the soft heel and a good fit thanks to the adjustable velcro strap keep her comfortable. She loves seeing all the big kids at our summer camp in Keens too!

    Are these waterproof! They stay damp

    4

    I love the traction, overall on/off ease and style. But I don't understand how these are "waterproof". They stay damp for hours and hours after water exposure. Am I missing something?

    I would buy this shoe again!

    Keens were recommended by a physical therapist for great arch support and sturdy sole. This shoe lives up to expectations and looks great too! Very easy to wash. Had to order a size up. The size chart indicated my toddler was a 6 but had to exchange for a 7, her toes were cramped in a 6.

    Time for my yearly Keen sandal purchase.

    I used to live in salt water sandals in the summer, but since I found these Keen's I won't go back. I get one or 2 new pairs every summer & wear them daily for the 3-4 months of nice weather we get here in western Oregon/Washington. Super comfy, and my heels and toes are covered. The heel cover is the one difference between kids and adult versions of this style. It keeps my heels from cracking. Also, I can get these wet and they just bounce right back. Getting them on sale is a bonus.

    Love the versatility of these shoes! Great for summer! (Would have given 5 stars if it weren't for an exchange issue I had.)

    Wonderful shoes for a new walker!!

    The shoes are wonderful for my one year old they are comfortable, supportive, stylish, no need for socks and not easy for her to pull off and throw like most of her other shoes! We're lifetime customers for sure!!!
