The ideal balance for people who want a light boot suitable for crampons. Featuring the same abrasion resistant and waterproof Cordura®upper of the Trango S Evo, and a Gore-Tex®/Duratherm® membrane, that guarantees waterproofness and breathability, combined with an antishock HP3 midsole.

UPPER

The Trango Extreme Evo Light GTX Boots by La Sportiva are technical mountaineering boots designed for the modern requirements of the alpinist, ice climber, and hiker: waterproof, lightweight, insulated, high performance. The ideal balance for people who want a light boot suitable for crampons. The upper is using Water repellent Cordura® with hydro-treatment + Flex Tec 2. They are lightly insulated so I wouldn’t do serious winter climbs in them if there is any chance of an unplanned bivy. Lined with Gore-Tex Insulated Comfort. This means your feet will stay warm and dry and water cannot get inside. Though, for the conditions of Greece (where I mostly climb), I believe is an ideal boot.


MIDSOLE, OUTSOLE

The mid-sole is made from EVA foam and compression-resistant Polyurethane. These shoes also come with an impact brake system for a better grip and nice cushioning – very comfortable especially when going downhill. With the climbing zone you will get on fine on the rock and the Crampons are perfect for alpine climbing. These boots have a    6-7 mm rigid HP3 midsole and can accommodate step-in (automatic) crampons which is perfect for any type of alpine and/or ice climbing.

New exclusive sole with the innovative technology IBS (Impact Brake System), developed in collaboration with Vibram, designed to soften impact on hard ground. The IBS (Impact Brake System) innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill.
Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.

Warmth/Comfort/Performance

These boots are really impressing. They fit perfectly and offer all-day comfort whether it be a 12 hour day climbing in Vardousia Mountains , or a single day ascent on Parnassos mountain. The boots are rather warm for the conditions in Greece, though I have some concerns about the warmth for any winter climb in the Alps.

The Vibram sole seems to give great grip on most surfaces and its stiffness is more than adequate when required to kick steps into bullet-hard snow. The sole is stiff  but walking comfort is not sacrificed, something that is aided by the anti-shock midsole. Heel and toe welts enable full step-in (C3) crampons to be attached securely.

The boot uppers are completely synthetic and they are remarkably tough; a friend of mine stumbled backwards and stood on my toe-box, full force with his crampon.
