Adventure-Ready Style with a Low-Profile Design
The Gypsum features a lightweight, flexible design with tonal stitching accents, a sleek silhouette, and a lace-up front. The neutrally colored upper showcases pops of color on the laces and around the heel.
Waterproof Upper Offers Breathable Protection
Because conditions can change suddenly, the Gypsum provides a range of different moisture-protection features. The waterproof upper keeps water out while still allowing your foot to breathe. For an additional layer of breathable protection, the Gypsum has a Keen.Dry waterproof membrane and a Dri-Lex collar that wicks away moisture and vapor to guard against odor.
EVA Midsole and Footbed for Optimum Support
For exceptional support throughout your day, the Gypsum has both a dual-density, compression-molded EVA midsole and a removable Keen Metatomical EVA footbed that provides arch support by hugging the natural contours of your foot. Additionally, Keen.Zorb Strobel--a full-length, foam-based cushioning layer--delivers a comfy, broken-in feel from the first step.
TPU Shank Reduces Foot Fatigue
To keep you going longer, the Gypsum's midsole has a torsional-stability shank made of TPU. This shank helps stabilize your foot as you move, reducing fatigue so you can go further, see more, and feel better when you get there.
S3 Heel Support
S3 stands for Shock, Suspension, and Stability and refers to Keen's unique heel-support structure. S3 is engineered to support the foot on impact, dissipating shock and helping to prevent ankle injuries.
Multi-Directional Lugs for Greater Traction
To give you a steady grip on a variety of terrain, the Gypsum has 4-millimeter multi-directional lugs on its non-marking rubber outsole. Because they're spaced wide on the sole, these lugs "bite" into the terrain, giving you more dependable traction on slippery and uneven surfaces.
Patented Toe Protection
Because rocky objects and debris can trip you up on the trail, most Gypsum styles include Keen.Protect, patented toe protection that wraps up and over the outsole for thorough coverage of the entire toe bed.
Keen: A Story of Hybrid Innovation
Keen began in 2003 with an inspired sandal design that combined comfort and toe protection. This radical design departure for sandals spawned the overriding Keen philosophy of hybrid innovation--striving to create new possibilities and to discover and implement original ideas.
Keen products put an emphasis on the joys of play. At the same time, Keen believes in the value of working hard to give back to the community. To that end, the company has partnered with non-profit organizations around the world to help get youth into the outdoors, protect land for its environmental and recreational value, and to give bikes to kids in need.
