Awesome boot. It's not as narrow as some would say. I do not have a narrow foot at all and these fit perfectly. Also, the fit around the foot and room in the toe box can be customized by adjusting the removable tongue.

Excellent design and thought went into these. I love them. They are very warm, but at really high and extreme situations you would still want a double boot like the Nuptse, in my opinion plastics are in the past. Besides the Nuptse, these are the best boots I've ever had.
