Please choose a size!

This kids' shoe looks like an old-school climbing design, but the soft, flexible material makes it ideal for everyday play. A padded collar cradles the ankle, and a mesh lining adds breathability.

  • Cleansport NXT™ for natural odor control
  • Padded collar for comfort
  • Secure fit lace capture system

We recommend you clean these products using mild soap and cold water. To remove excess dirt or spot clean, use a stiff brush or soft cloth. Let shoes air dry away from heat.

    The shoes last on and on and on!! I think they might last forever!! My grandson is the ROUGHEST kid on shoes, but they have lasted a whole school year of Kindergarten and STILL look great and like new! WARNING: They run really, REALLY small!!! At LEAST one size...maybe 2! He now NOW can wear a 13 in his Keen sandals, but he just outgrew his size 1 in this shoe!! Plan accordingly when you buy!!

    They go on and off easily, yet stay on when walking and hiking.

    My daughter had the Little Kids Jasper and outgrew them, she immediately told me she wanted another pair. I knew I could get a larger size and didn't hesitate. She wore the last ones to school everyday and didn't wear them out. Love a shoe that survives an entire school year.

    Durable and comfortable

    My son is 5 and tough on shoes. He has a wide toe box, and is very active, so he needs a durable shoe. So far, these have done the trick. I am thinking of buying the same shoe in the next size up so that we are not looking for something else when the time comes. He had a pain of Keen's a couple of years ago and they were great. We went to other brands, but these seem to fit better and last better than the others. You can buy a cheaper shoe - but you get a cheaper shoe.

    I got a pair of these for my 5 year old and I love them! He does have a more difficult time getting them on his feet on his own, but I think it is time to buy him a shoehorn for Christmas. I love that he doesn't have to tie them so they go on quick!

    My son is very rough on his shoes - a typical tennis shoe is typically destroyed after 3 months. He loves these because he can be as rough as he wants and be comfortable.

    look great but snug

    I bought these one size up for my 6 year old and we couldn't get them on so I bought another pair two sizes up and they are also snug. But his old shoes fell apart so we had to keep these. They are a struggle to get on but are roomy and comfortable once on. They won't fit for long!

    Slick soles and broken laces after 3 months

    I have purchased Keens for my husband and 4 boys for years and they use to hold up really well. The last few times I have ordered, there have been issues with the shoe breaking down prematurely. This pair, in particular, is only 3 months old and the bottoms are slick. The elastic laces have also broken and had to be replaced with regular laces. My son is 8 years old and wears them to school, I fully expect Keens to withstand daily wear.

    My 6 yr old grandson Wilder Loves his new shoes. His name matches the needs of his wardrobe, so the Jasper shoe is a great fit. Comfortable, easy to get on and off, great color and they move with him.
