In Love
I’m in love with these boots out of the box and haven’t even heat molded them yet. I’m a lean guy with not only thin legs, but thin feet. The double boa is a game changer for me, I get to the exact tightness I want to I don’t move, but stay comfortable. The micro adjustments are so easy I can even spin the dial forward and back while riding the lift over my pants. Everyone’s anatomy is different but if you are thin and calf challenged - I think you’ll really love these boots. That said, make sure you need a narrow fit or you won’t even be able to put these on.

Loving double boa
Yes , I recommend this product
I have narrow feet and thin legs and needed a low volume boot. Most of those boots come in a stiff flex, so I was really happy to find these in a 100 as I prefer all day comfort over performance. I believe this is the first model of this level boot with a double boa and it exceeded my expectations. I love becoming to make micro adjustment with just a click, and I even adjust on the lift, being able to turn the dial over my pants. If you’ve got lean legs, odds are you will really love this boot.
