    Fit just rightI’ve tried a couple of brands of plantar fasciitis socks and these fit the best. The compression isn’t too much, but they’re supportive when I’m running.

    BreathableThese socks are very comfortable and breath well. The compression is nice, it's not too much. I have really enjoyed the socks. - Christian
