Good to know

  • The La Sportive Olympus Mons Cube men's boots are the updated version of the Olympus Mons Evo. The Cube version features tech fitting binding inserts that allow for skiing across and up glaciers. This is especially helpful for polar expeditions that require a long approach on skis.
  • Despite the added features, the latest Olympus boots from La Sportiva is 400 grams much lighter than its predecessor. It's also warmer due to the addition of the Primaloft Gold Insulation Aerogel. It also features a thermally insulated outsole by Vibram.
  • Instead of laces, the new Olympus Mons features a BOA system - a dial closure that makes it possible to adjust the tightness of the boot even with your gloves on.

The Olympus Mons Evo Cube is essentially a triple layer boot. In addition to the second-layer boot, there is a third sock liner for a glove-like fit. It also adds warmth and comfort to the foot and helps increase the drying times significantly. The boot also comes with a gaiter with an offset zipper that goes its full length. This design allows flexibility and easy access inside. The waterproof zipper is reinforced by a heavy-duty Velcro fastener. 

Instead of a lace-up closure, the Mons Evo Cube uses the dual BOA system that lets the wearer adjust the fit between the upper and lower portions of the internal boot in one go, and without the wearer having to take their hand gloves off.

The Olympus Mons Evo Cube has the Vibram Litebase and Morflex outsole which is about 40-50% thinner than their standard outsole but has the same performance and durability, thereby reducing the overall weight of the boot. The wide spaces between the lugs ensure that no dirt, snow, or mud get stuck in between.

For the midsole, this mountaineering boot from La Sportiva uses a 2mm polyurethane for crampon attachment. A big change in the current Olympus Mons are the tech inserts that allow the boot to be used with mountaineering bindings at the toe only. 

Compared to the previous version, the Olympus Mons Cube has a slimmer upper which is composed of a hard-wearing Cordura gaiter, a robust outer shell, and two inner thermal booties. The thermal insulation is enhanced by the Primaloft Gold Aerogel that is designed for freezing weather conditions. 

-The La Sportiva Olympus Mons Cube has won Gold at the 2019 ISPO Awards.
