Product Care

Sandals

All KEEN water sandals are machine washable. Use a small amount of detergent, wash on gentle cycle and air dry.

Leather

We've carefully selected leather uppers designed to last. Then again, if you're wearing your KEENs daily, they won't always be scuff and dirt-free.To treat day to day wear and tear, especially on lighter color leathers, we recommend using a leather cleaner and conditioner, found at most footwear dealers and/or shoe repair shops.

Non-Leather Hiking

Gently brush the shoe 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. This process may cause slight discoloration to the area.

Canvas

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.

I really love the look

"I really love the look and quality of the Keen Jasper. I’ve owned several pairs of Keen shoes over the years, and they have always impressed me. Although the Jasper is an urban, hiking-inspired shoe, I find it a little too soft and flexible. I would have preferred a stiffer shoe with more support for walking on uneven terrain. I also think Keen could improve the outsole by giving it a grippier tread pattern to provide better traction and confidence on rough surfaces"
