The Keen Revel III is a comfortable and warm boot that didn’t require a break-in period out of the box. The footbed and outer sole are stiff and provide great traction on icy terrain, but the upper is too flexible to provide adequate ankle support. Compared to other boots, the Revel is extremely comfortable for both narrow and wider-foot hikers, but could improve with stiffness in the upper around the ankles.
Versatility The Keen Revel III fit well with snowshoes and microspikes, and worked well for a variety of lengths of hikes on unsteady and snowy terrain.
Comfort The Keen Revel III boots have a roomy toe box and decent arch support with the provided insole. The boots fit snug with a cushy collar and no break-in period.
Traction On ice and slick snow, the Revels faired well, providing good traction and little slippage due to the Dual-climate rubber outsole and medium lugs for ice and snow.
Warmth On a six-mile snowshoe hike in deep snow, the Revel IIIs kept feet warm in all conditions. With two different types of insulation—Keen.Warm on the top and a tri-layer Heat TRAPOLATOR system underfoot—and a waterproof membrane, feet didn’t chilly or get wet.
Stability The stiff footbed provided support on uneven and rocky terrain, while the flexible upper kept the boots comfortable with no hot spots developing on initial hikes. A more stiffness in the upper near the ankle could help provide more support for the ankles.
