  • The La Sportiva G2 SM is a high-cut double boot that’s designed for mountaineering in cold environments. Its gaiter and outer boot are made primarily of lightweight Cordura material. The inner boot, on the other hand, uses a PE and EVA construction for better heat retention.
  • The boot’s polyurethane (PU) midsole provides sufficient stability and cushioning. It’s also compatible step-in crampons.
  • Surface traction is handled by the gear’s Vibram Matterhorn outsole. It is fitted with an Impact Brake System which aids users during descents.

The La Sportiva G2 SM is a fairly true-to-size Unisex alpine boot. It’s offered in standard width. Whole and half sizes are available. Per the brand’s sizing chart, women should go one size down to get the correct fit in this boot.

A customized fit is made possible by the outer bootie’s Dual Boa lacing system. It uses a set of dials that loosens or tightens the laces. The inner boot has a dual hook-and-loop closure lacing system while the gaiter is fitted with a zip closure feature for a secure fit.

The G2 SM from La Sportiva is equipped with Vibram Matterhorn a mountaineering outsole that maintains its grip performance in low temperatures. It features an Impact Brake System that creates a stopping force when going downhill. The outsole’s lug pattern is set in opposing slanted directions to increase braking capability by an average of 20%. This technology also lessens impact forces by around 20%.

The La Sportiva G2 SM has a 2mm polyurethane (PU) midsole to supply cushioning and support. It has toe and heel welts for attaching crampons. The mountaineering boot also comes with a 3 mm Honeycomb Tech insulating carbon insole that grants lightweight underfoot comfort.

The G2 SM’s upper consists of three components – the gaiter, inner boot, and outer boot. The gaiter is made of a lightweight material called Cordura, a special kind of fabric that’s designed to be tear-resistant. It also possesses a laminated and taped membrane for added water resistance. The cuff is made of an elastic Cordura variant to allow more flexibility to the boot’s user. Moreover, its zip closure system allows a secure lockdown while a nylon pull loop adjusts the fit of the gaiter.

The La Sportiva G2 SM’s outer boot incorporates a combination of low-density PE foam, thermo-reflective aluminum and perforated felt to achieve insulation. Parts of this gear contain Cordura and Antiacqua-coated-Lorica, a kind of synthetic leather, for durability, breathability, and water repellency. A Dual Boa closure system provides a personalized lockdown.

This Lowa product’s inner boot is made of 6mm PE and ethylene-vinyl acetate (EVA) foam for extra warmth.  It features a Cordura Flex Zone, which grants flexibility. A dual hook-and-loop closure system gives a secure lockdown with easy adjustability.
