G2 Evo is the ultra thermal double boot for extreme mountaineering and prolonged use at low temperatures. It provides maximum water repellency thanks to the internal thermo-taping and the innovative UltraSonic Welding technology which allows the materials to be joined together without the need for stitiching, the external anti-drag materials and to the internal insulating package of the shell. Resistance to abrasion is guaranteed by the use of Cordura®. The bootie is made using quick-drying materials to allow prolonged use in the mountains. Volumes and weight are extremely contained thanks to the Honeycomb Tech midsole in carbon fiber and to the compact, high-performance construction in traditional La Sportiva style. The inner shell adopts the BOA® Fit System quick-closing system in a double configuration that guarantees a fast, easy and precise fit and differentiated shell tension between the upper and lower part. The BOA® Fit System placed outside the gaiter allows the closure to be adjusted without having to open the zipper of the external gaiter, ensuring the maintenance of the internal temperature and the possibility of acting on the closure system without removing gloves.

servizio eccellente, prodotto acquistato che rispondeva alla descrizione del sito, tempestività nella consegna. giudizio positivo
Testato isolamento fino a 6150 m, anche in presenza di vento. Globalmente il prodotto si è rivelato adatto agli scopi per cui è stato pensato e fabbricato. Unico appunto: calzare e levare lo scarpone risulta un po' difficoltoso data la precisione della scarpetta interna, specie se tale operazione deve essere effettuata in tenda. Sarebbe auspicabile che la scarpetta interna, una volta estratta dallo scafo esterno, potesse essere impiegata anche come calzatura per camminata, come per altri precedenti modelli. La mancanza di tale possibilità obbliga a ricalzare ogni volta l'intero scarpone. Preciso, rapido e comodo, per contro, il sistema di chiusura a doppio boa, in particolare quello esterno che regola la chiusura dell'avampiede. Apprezzabile, in ultimo, la complessiva leggerezza dello scarpone.
Amazing product, if you’re mountaineering I would recommend to invest in this if you want to have your feet well insulated

Impact Break System Mountaineering

The 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.
