Even in the heat of the summer you still need a hiking boot like the Keen Gypsum Mid Waterproof Hiking Boot to protect your feet from the elements and keep you comfortable and dry throughout. At the trail head it could very well be balmy, but twenty minutes into the climb you could encounter a hail storm, raging stream or challenging crags. The Keen Gypsum fights back with a combination of nubuck leather and waterproof breathable membrane, along with an in depth lacing system, ESS shank and TPU stabilizer to help keep the foot stable and secure. If needed, the removable EVA footbed allows you to further adjust your comfort level. For traction on tough climbs, there's nothing better than the Gypsum Mid Waterproof Hiking Boot's rubberized outsole, which curves up around the boot at ground level for added support and durability. In addition, the sole features 4mm multi directional lugs for confident traction anywhere along the trail. The Keen Gypsum may be perfect for summer wear, but it can easily be worn as a four season boot, repelling winter snow, spring rains, summer heat and autumn chills.
