Keen Revel IV Mid Polar Walking Boot

No need to wait for someone else to make first tracks. Keen have given their waterproof winter boots their warmest insulation, plus better grip for snow and ice.

Waterproof Leather and Performance Mesh Upper

The waterproof leather upper provides exceptional protection and stability against the cool, wintry conditions. Your feet will remain warm and dry thanks to the waterproof properties which repel the wet weather so you can maintain focus and performance. Working alongside the leather is Keen Warm insulation which works to keep your feet dry and comfortable by preventing weather entry in addition to allowing your feet to remain insulated. In addition, Keen Dry technology is also used as a proprietary waterproof, breathable membrane that lets vapour out without letting water in. As well as providing protection and comfort, the shoes promote efficient moisture management by wicking away the build-up of excess sweat and moisture to leave your feet cool, dry and comfortable. The gaiter ring hook enables you to fasten your gaiter to the shoe to protect you from debris and walking in intense conditions such as snow and ice.

EVA Midsole

Compression moulded EVA in the midsole provides cushioning and comfort for whilst you're on the go. Towards the top, the EVA is extremely spongey and cushioned, which will bring lasting comfort that will reduce the stress placed on joints like the knees and ankles. This will, as a result, reduce the risk of injuries and the effects of fatigue. Towards the bottom, the EVA is firmer, and this will instantly absorb shocks from the uneven surface below, protecting the sole of the feet from damage. The firm sides on the midsole will also provide protection to the foot and to the boot in general, stopping superficial damage from occurring. Giving you an added spring in your step, the midsole can flex which will react by giving you an added spring, which will give you a little extra boost to help keep you going for longer. A Thermal Heat Shield insole system works by having three layers of innovative heat-trapping materials which are then sandwiched underfoot to hold warm air in. This process works a lot like the insulation seen in houses. A thermal heat footbed situated on the outside delivers woolly softness; in the middle, support cushioning; and inside, a thermal foil barrier to harness radiant heat. The footbed actively and effectively keeps the cold out and the heat in.

Keen Polar Traction Outsole

The Polar Traction Outsole is ideal for an array of surfaces to provide you with an assured footing, even on the most unpredictable or difficult terrain, including snow and ice. Having the 5mm multi-directional lugs ensures exceptional grip and traction, perfect for your outdoor adventures. The dual climate nature of the outsole helps to focus on conditions such as ice and snow, where a regular outsole would not suffice. Primarily the shoe is designed for winter, but the versatility ensures it can be worn equally well in warmer conditions. Well-made and durable, the outsole provides stability to be a long-lasting, reliable and essential addition to your outdoor attire.
