Familiarity: I've put it through the wringer
Fit: True to size
If the boots fit your feet, they are hands down an amazing boot. they stick to everything, are super adjustable, fit my crampons wonderfully, and flex well when approaching and down climbing.
One issue that i have is my right foot is smaller than my right resulting in some heavy blistering on the smaller foot from heel lift. The tread wears pretty fast, so limit the time you spend walking the streets of Chamonix.
Do yourself a favor and get these the same size as your street shoes, and add a quality insole. I do no recommend "sizing up" to accommodate thicker socks for added warmth - this will lead to heel lift and reduced circulation in your feet from tying the laces super tight.
These boots have basically zero insulation and at 4800 meters, my toes were ice. if you are climbing in 0 C or above, these will be perfect.
I recommend trying these on in the store and spending no less than 15 minutes walking around in them. I wear a 43 in asolo boots and ordered a 43.5 (too large) returned for a 43 with no issues in heel lift or toe jam as long as the boot is laced properly.
