  • 【Stirling engine】A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall.

    Comfort!
    Size: One Size, Color: (100) White / White / Halo Gray
    Very comfortable! Thinner than the picture shows, but I like the fact that they are no show but still higher in the back and front to protect my heels and such.

    Sizing way off
    Size: One Size, Color: (100) White / White / Halo Gray
    These were my favorite socks, at least the old style was. They redid them and I was okay with it. However, I don't understand how they are a one size fits most. I tried them on and they were still too big at the top. There was so much extra fabric at the toes. For reference, I wear a size 8.5 women's shoe, typically. The packaging says fits most from size 5.5 to 12. I don't understand how it fits that wide range of shoe size. Definitely returning these and I will be buying something else.
