    Not bulky fit
    Size: Large, Color: (009) Gray Dawn / White / Prime Pink
    Thinner than UA other cushioning run socks, but this fit is perfect and doesn't shift in my shoe. I wear a women's 9.5 and determined Large doesn't squeeze my foot like Medium size (too exact). Bonus... avaliable olors beyond black and Grey.

    Love these socks!
    The wife struggles with socks. She only like the Nike ones, then they discontinued them, so had to start the search again! Found these, they are expensive just like the Nike, but the size is true, they look great, they are super soft and stretchy. They are light weight and breathable and seem to wick away moisture. She loves these!

    Great quality.
    Size: Large, Color: (001) Black / Black / White
    Thickness and comfort are great. Quality is great and the same I would expect if I bought at the branded storefront.
