A+ Fit

I've used it once or twice and have initial impressions
Size Bought:
6' 2"

These perfectly fit my splitboard boots (10.5) with plenty of room to spare. The heel of the crampon is wide and fits the boot like a glove. Easy to breakdown and pack into the petzl fakir bag, and fit into my backpack. Couldn't be happier with these.

Would not recommend for small feet

I've used it several times
Size Bought:
One size
5' 5"

I bought these to climb Mt Rainier during a glacier course. From the first day, I had an issue with the front latch unclipping which would lengthen the crampon. My guides tried to tweak it and tied it as tight as we could to get away with it. Then on summit push that happened repeatedly, creating a very dangerous situation for me given it was such a critical piece of gear. We had to stop mid route twice to retighten the crampons which was not ideal. At the summit, my guide switched our crampons because his bigger feet would not have the same issue. I would NOT recommend these to people with small feet. I’m a size 7 street shoe size (my mountaineering boots were 1 size up).

Fits great

I've used it once or twice and have initial impressions
Size Bought:
5' 8"

Sturdy fit of lever lock on Asolo and La Sportiva boots with toe/heel welts. Looking forward to using these on Mt Rainier and possibly Denali. Easy to get good purchase on hard ice and no issues front pointing.

Petzl Vasak Flexlock

Size Bought:
One Size
6' 3"

I just received these crampons after speaking with customer service, and they fit my size US size 13 (48) Zamberland Vioz 1996 GTX boots perfectly (any larger size likely wouldn’t fit the crampon). They are snug, have zero wobble, and fit flush on the bottom of the boot. I will update after using them on my trip out west.
