Men's JASPER

$140.00

  • Style #1018203
  • Fit Tip: This style is running a 1/2 size small. We suggest ordering a 1/2 size larger than your usual size! Size Guide
Please choose a size!

Reward your ever-wandering feet with the Jasper from KEEN. The cushioning cork and latex footbed conforms to your foot's natural shape. The efficient design is easy to pack for a comfy after-sport shoe that will have your feet rejoicing after a long day of play.

  • Climbing inspired upper design
  • Lace to toe extended lacing system

Gently brush the footwear with a soft bristle brush or hand towel to remove loose dirt and debris. Stains can be treated by lightly rubbing a gum eraser in a circular motion over the location and lightly brushing afterwards. Tough stains can be treated with a mixture of water and a little vinegar on a damp cloth. Follow this with a light brushing. Voila! Clean shoes. This process may cause slight discoloration to the area.

    I have always liked the way Keen shoes fit and this pair is no different.

    Stylish footwear

    4

    I like these shoes a lot. The look good and seem well made. I ordered a half size larger than my normal and they fit well.

    undisclosed

    I would buy these again.

    Very, very comfortable but tend to be a bit warm in summer.

    Good shoe, comfortable, only one very minor complaint

    4

    Fairly comfortable right away. I ordered 1/2 size bigger than usual and they fit well. I actually wish the tongue was a little bit stiffer, because occasionally it gets folded over when I put them on and then I have to straighten it out or it will be uncomfortable. Other than that, they are great.

    undisclosed

    I will be back

    Really comfy shoes, they are working great for long walks around san francisco streets. I will shop at keens again.

    Make mine Keen!

    I love these shoes! I liked them so much; I bought a second pair. I think the last 10 pairs of shoes I have bought have been Keens. I love the quality and cool styles.

    Ruggedly hip

    Our son, Jeylin, loves his hip, new, comfy, purple Keens! Functional, stylish AND rugged. Thanks, Keen!

    Great for my arthritic knees

    5

    I have struggled to find shoes that do not impact my arthritic knees condition. Through research I found that footwear that closely resemble walking barefoot were my best bet. I have found that the Keen's Jasper model closely replicates walking barefoot. Also I did not want alot of squishy padding which seems to constantly cause my knee issues while walking. The Jasper meets all my needs and I intend to purchase Keen shoes again. In the past I have used New Balance, Nike, Brooks, and Merrill which all failed in providing the proper support for my condition.

    I'm not finished shopping with Keen!

    They are excellent! A little heavy but still wonderful!
