Grippy outsole

Giving the KEEN Whisper traction on rugged terrain and urban surfaces is its non-marking outsole. It’s a grippy, single-piece rubber that features multi-directional lugs and extends all the way to the upper’s forefoot zone, which acts as a protective barrier against forefoot injuries and toe bumps.

Gentle support in the KEEN Whisper

With its compression-molded Metatomical EVA midsole, the Whisper renders cushioning and stability at the same time. It runs thick, especially around the heel zone for added comfort, and comes with a TPU stability shank for extra support.

Odor control technology

The KEEN Whisper's insole is engineered with Cleansport NXT — a technology that fights odor on a micro-level. It is also textured for an extra underfoot grip.

Breathable fast-drying upper 

The KEEN Whisper’s stitched upper is a combination of polyester and hydrophobic mesh materials that make the sandal breathable, lightweight, and washer-friendly. Breathability is also achieved through the upper’s numerous vent holes.

KEEN's extra secure fit

KEEN’s secure fit lace capture system is the footwear’s primary source of ankle lockdown. It makes lacing up a smooth experience, thanks to its elastic speed laces, loop eyelets, and an adjustable locking clip.

On the back of the heel, the sandal comes with a pull tab for easy on and off. Reinforcing the forefoot zone of the Whisper, on the other hand, is a toe guard.
