The toe box is a bit narrow for me when wearing winter socks, but not uncomfortable. Besides the toe box everything else is as I expected in a good pair of mountaineering boots, and the delivery was on time.

Hello, this model will fall short for your necessities. To climb up to 6500m we recommend you the Millet Davai Cordura Primaloft. This model is thermal-controlled and more technical. https://www.trekkinn.com/montana/millet-davai-cordura-primaloft/42297/p Regards
