Product Description

The official choice of the Chamonix Guides Company for their 4-season mountaineering performance, these technical boots in Gore-Tex Duratherm offer all the protection and precision demanded in the high mountains. With a membrane directly bonded onto hollow fibers, the Grepon 4S GTX is 100% waterproof, breathable and withstand the cold very well, providing the insulation needed below zero. At ease on ice and large rocks, they meet the challenge of vertical ascents with their stiff build, which gives the feet maximum support when front-pointing, with optimal lightness. The Vibram Mulaz Evo outsole is precise, high-traction and lightweight, with a slim toebox. The side AFC structure, the fruit of lengthy Millet expertise, offers ideal heel hold and increases toebox feel. Hybrid crampon compatible, easy to handle, and high-quality Italian manufacturing.

Comfort membrane from Gore-Tex. Gore`s research and development offers a material enhancing long lasting comfort with excellent breathable, durable waterproof and windproof properties.

The Vibram outsole forms a sturdy barrier between feet and ground. It stabilizes the foot and has a high grip.

Shoe very comfortable on all terrain alpine hike, good grip on the ascent and descent, very good for long runsde plus it is light, the heel is very well held, the lacing is well thought out, do not touch the toes in downhill mode. Until then no blisters ...

Chaussure très confortable sur tout les terrains rando alpine, bonne accroche à la montée et à la descente, très bien pour les longues coursesde plus elle est légère, le talon est très bien tenu, le laçage est bien pensé, on ne touche pas les orteils en mode descente. Jusque là pas de cloques...

Translated from German To the original

The shoe meets all my requirements for my slightly wider feet with high instep. The heel sits and there is also no bubbles on the first tour over 20 km. My slightly exposed ankle is not subjected to pressure and so this shoe is for me the best for years. Due to the carbon insoles, there are no pressure points on the underfoot in the coarse gravel. The hold and the roll-off behavior (strong-looking) is very good. After several buy-outs from other Bergschuhmarken, I got another pair of Millet Grepon 4S GTX.

Der Schuh erfüllt alle meine Anforderungen für meine etwas breitere Füsse mit hohen Rist. Die Ferse sitzt und es gibt auch bei der ersten Tour über 20 km keine Blasen. Meine etwas exponierten Knöchel sind keinem Druck ausgesetzt und so ist dieser Schuh für mich der beste seit Jahren. Durch die Karbonzwischensohlen ergeben sich keine Druckstellen auf die Fussunterseiten im groben Geröll. Der Halt und das Abrollverhalten (kräfteschonend) ist sehr gut. Nach etlichen Fehlkäufen von anderen Bergschuhmarken überlege mir ein weiteres Paar Millet Grepon 4S GTX anzuschaffen.
