The La Sportiva Olympus Mons EVO Boot is a double boot for high
altitude mountaineering. When the peak is 8000 meters, the conditions
turn from harsh to extreme and your feet need all the help they can get
out there. At 49.86 ounces, these puppies are considered lightweight, so
step inside and just revel in the PE thermal insulating inner boot. The
outer boot has a Cordura® lined upper with some closed cell foam to
insulate, as well as a Vibram® rubber rand for plenty of durability. The
built in gaiter comes up high, preventing snow and water from soaking
on in with Cordura® and Kevlar® fabrics that are incredibly durable and
waterproof. With or without crampons, these monsters will help you climb
to the top.
