Features
  • Easy-On Bungee Cinch. Keen's Easy-On Bungee Cinch closes the fit behind the heel, so the slide goes on without hands. Keen put it plainly: slips on, stays on, with feet staying secure against the small heel.
  • Instant comfort underfoot. A microfiber fleece lining over supportive cushioning, on Keen's iconic room-for-your-toes fit. Built for bare feet rather than socks.
  • Outside traction. A rugged, higher-traction rubber outsole takes this outdoors as well as in — Keen describe it as a slipper for outside. The rubber is non-marking, so it will not streak a hardwood floor.
  • KEEN.PROTECT toe bumper. A KEEN.PROTECT toe bumper runs across the front of the slide to shield the toes.
  • Eco Anti-Odor. Keen's Eco Anti-Odor gives natural, pesticide-free odor control, which matters on a slide worn barefoot.
Size & Fit
  • Original Fit has generous space across the forefoot for toes to splay.
  • Offered in men's 8.5–14, including half sizes.

How to measure: stand on a piece of paper and mark the back of your heel and the tip of your longest toe, then measure the distance in centimeters. If one foot is longer than the other, use the larger measurement and match it to the closest Heel-to-toe value in the chart.

Fit notes: every KEEN starts with a secure heel fit for stability, with room in the toe box for toes to splay. KEEN footwear is built on an anatomical last with fine-tuned arch support and cushioning, and protected by KEEN's iconic rubber toe bumper.

Cushioning

KEEN: "bare feet love the microfiber fleece lining, supportive cushioning, and iconic room-for-your-toes fit." Supportive rather than soft underfoot.

Versatility

Goes anywhere

KEEN calls it a hybrid comfort slide: "super comfy inside, with traction for outside," where a rugged rubber outsole makes it "like a slipper for outside."

Best for

Is this right for you?

Around the house

The pair you put on the moment you get home. Super comfy inside, in Keen's own words, and the room-for-your-toes fit lets the foot spread out after a day in shoes.

Not for: Not a stand-in for a shoe if you are on your feet all day on hard floors — this is a slide, open at the heel. More slip-ons, clogs and slippers

Vanlife and camplife

Keen file the Howser III under Vanlife & Camplife. It goes on without bending down, the bungee holds it on uneven ground, and the rubber outsole handles the walk from the van to the firepit.

Not for: Not a camp shoe for cold or wet nights — there is no insulation and no water rating. More Keen

Quick trips outside

The dog walk, the mail run, the gravel driveway. The rugged rubber outsole is what separates this from a house slipper.

Not for: Not for hiking, snow or anything that needs a closed, secured shoe. All footwear

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
Do these run true to size?

Yes. The Howser III is built on Keen's Original Fit, which leaves generous space across the forefoot for toes to splay, so most people take their usual size. Keen publish the men's model in 7-15, regular width; Mountain Sports carries men's 8.5-14, half sizes included.

Can I wear them without socks?

Yes, and that is what it is designed for. Keen build the Howser III for bare feet — a microfiber fleece lining underfoot and the Eco Anti-Odor treatment for natural, pesticide-free odor control.

Can I get them wet?

Keen publish no water rating and no water-friendly claim for the Howser III, so treat it as a dry-wear slide. The upper on this colourway is natural felt, which soaks up water and is slow to dry; if it does get wet, air dry it at room temperature away from heat.

How do I clean them?

Gently brush with a soft, damp sponge to lift loose dirt, and treat stains right away with a gentle cleaner. Air dry away from heat. Keep them out of the washing machine and the dryer.

Is the insole removable?

Yes. The insole lifts out, so you can take it out to dry, clean it separately, or swap in your own.
