Great mountaineering boots! - Scarpa Phantom Tech Mountaineering Shoes

Overall great mountaineering boots, the only thing that I do not enjoy about these boots is the lace locking system which feels like a overly complicated design. But this is not a deal breaker for me since overall design is pretty great and you don’t find features like super gaiter and great waterproofing in other single insulation mountaineering boot. I wear a US9 for my casual/running shoes and had to buy US9.5 (EU42.5) for Scarpa Phantom Tech. Fits pretty well with heavy duty mountaineering socks. My feet is neither too narrow or too wide.
