I love these calf sleeves. They are on the expensive side. I only bought them because Sage Canaday recommends them. I doubt they're superior to cheaper alternatives but you never know.

They don't make you run faster or prevent injury. They are supposed to help mitigate some fatigue for long mileage & help with circulation.

I just like how they look. I feel like a 2:30 marathoner when I wear them.

Sizing is accurate. You measure your calf. Go to he website & itll tell you what size you should order based on your calf size.

Comfort: I can (and often do) wear these all day. I don't notice them. Easy to put on and take off. Not too tight and I have big calves.
