Men's JASPER

$90.00

  • 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! Please choose an inseam!

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.

  • Five Keen

    Well, I bought these for me. I love them! Comfortable wide toe box needed for my slim heel and wide toes, and thin sole none of this crazy build up so many shoes seem to think they have to have. I don't want shoes that have 2 inches of sole unless they are work boots. I have five current pairs of keens two uneek, These, hikers and steel toe work boots love​ them all.

    Awesome shoes! These felt and fit great right out of the box. They get compliments all of the time. Easy to care for and have worn well. Just a little sole squeak* that comes and goes.

    I just bought my second pair of Keen Jaspers. They are well-made, comfortable, and stylish. They run small, so order them a half-size larger than what you usually wear. I will almost certainly buy another pair when these wear out.

    When I was researching these I wondered why people owned more than one pair... now I know why 😁. These are my new favorite shoes. AND I will be buying another pair soon.

    It takes a few days to fully break in. But once they are, wow. I am generally on my feet for 8 to 12 hours a day. No tired feet. No soreness. I have mega wide feet and they fit great.
